I am trying to create a responsive navigation menu. I found some tutorials online and after finding one that I liked the style of, I followed the directions to create it on my website, but I can't seem to get a couple features working.
1: I can't get the hover effect to work that adds a bottom border to the icons/links to help accent the one that is in focus.
2: When getting down to a screen size that is below 32.5em (519px), the menu is supposed to become a single column menu that folds up. The menu does become a single column, but it doesn't fold up into a button like it is supposed to. It keeps displaying all of the links which takes up a lot of vertical space.
Here is a jsFiddle of my project so you can see what I have so far:
https://jsfiddle.net/4Ljs1bfn/1/
You need to use the js detection that the example uses.
Add class="no-js" to your body element.
Then on load, set document.body.className = "js" (or equivalent).
This will enable the menu.
For the :hover problem, you need the class="no-touch" on your body element (then remove it using js if a touchscreen is detected).
Another thing: You have a html error at <a href="...""> on line ~8 (that extra " at the end).
Updated fiddle: https://jsfiddle.net/4Ljs1bfn/2/. You still have some css issues, but I assume you can fix them yourself.

I made the following component in Angular.
It's basically a kind of tree component.
Please note the following:
The tree has several branches.
It consists of nodes in alternating colors.
And the selected node is marked by a blue dot.
The tree does not fit the screen, that's why there's a horizontal scroll bar.
Each node has a unique id (i.e. <div id="...">)
This component works fine, however. I don't know how to add the following feature:
When the focus changes, (in other words, a different node becomes active), I want this node always to be visible on the screen. That means that the webbrowser has to scroll to the left or right, automatically whenever a node is selected. It has to scroll or jump until the specific <div> is visible.
How can this be done using javascript or typescript ?
EDIT:
I want to use this javascript is the base for better navigation tools.
button to move back and forth in the tree
button to jump 10 nodes to left/right.
button to jump to the back.
button to jump to the start.
Also when a new node is added to the back of the tree, right now the user has to scroll all the way to the right, manually. I want it to be visible immediatly, automatically.
Those are my real objectives :)
If the only scroll mechanism you need is the automatic one, I would avoid trying to use the browser's built in scrolling mechanism altogether and just use ElementRef of the node to get its horizontal position relative to its container, and then apply a CSS 'translate' to move it as needed. It will be much easier this way to have it look "nice" with CSS transitions and animations. But if you would still need manual scroll behavior (i.e, the user still needs to be able to scroll with a scrollbar) youd have to program a scrollbar directive / solution as well, which may end up being more effort than the problem demands.
This page has a sort of hacky workaround for horizontal scrolling - https://css-tricks.com/pure-css-horizontal-scrolling/
The problem for me in the past with 'scrollTop' and 'scrollLeft' is you can't apply transitions to those attributes, so they end up looking very jerky without implementing custom easing functions in javascript.
So I have a website that has a hamburger menu on mobile.
The problem is that whenever the page loads on a small device, the hamburger menu is way outside the view port to the right. This causes side scrolling issues and tons of white space.
I originally assumed I had written some css that was causing this, but after experimenting, I've come to realize that I do not know what is going on at all.
I have Gifs of the problem. I will also provide a URL if needed.
Heres the first gif

So heres what is happening. I am inspecting the DOM of the webpage. If you pick any random element on the page, and edit a CSS attribute, then the menu fixes itself. It doesn't matter what element you select or what css attribute you edit; when you make an adjustment the problem is fixed.
Here is the second gif

In this gif, the issue is literally fixed just by activating a CSS plugin called pesticide. Pesticide simply adds another external css sheet to the document that outlines everything in blue. Notice that even when I turn off pesiticde, my issue has been fixed.
And finally the third gif

This is the most perplexing issue. It fixes the hamburger icon simply by resizing my browser screen. Obviously mobile users cant do this.
I truly don't understand this issue. I've tried to set a width of 100% on the nav element. I've written some javascript that when the DOM is ready, to add a css attribute to a a DIV in the footer and then remove it after a few seconds. This does not fix my issue. I would happily provide the javascript I wrote if requested.
Has anyone else ever had an issue like this?
EDIT
Here is another example. I use the browser Blisk to test my sites on multiple devices. Look at this
https://gfycat.com/BouncyFlakyGlobefish
When I first load up the site, I have my hamburger menu issue. When I tell the browser to view the site from a different device 'say switching from iphone 5 to iphone 6' it fixes the issue. I am so frustrated with this problem.
The white section's animation is increasing the width of the page (pushing the hamburger which is fixed to the right out of view), I'm not certain why this doesn't update properly after the animation is complete, but it would appear it requires a page re-flow before working correctly.
A possible CSS fix would be to add .bodymargins{overflow:hidden} though this may cause problems to other styling (untested on your site)
If this isn't an option, you could manually trigger a re-flow of the page shortly after loading (this is a slightly nasty option, but is better than it being broken)
Various re-flow options available here
It may be because you are using media queries and your browser width is not yet small enough for them to fire when you test.
If not, make the media queries and don't use the margin-left:auto for the smaller screen size?
I'm seeking to emulate the on-clickable input forms that pops up when an user clicks on the blue bar as shown above. My experience with front-end development is limited so I don't know what to call these elements exactly, but let's say they are on-clickable input forms contained in a box, which can lead to other on-clickable forms like the date picker as shown.
How do I do this in Javascript? Preferably with AngularJS, since the app I'm working on uses that. I don't mind using JQuery though.
I'm not looking for detailed step-by-step instructions (which I don't mind), but hints to get me started on cloning these features.
Thanks.
The pop-ups you see are going to be HTML elements, probably <div>s. The page will use JavaScript to create event listeners on the bars to hide/show them when the bars are clicked/moused over. The "pop-ups" are really just like any other element in the page, but with a higher Z-index and using CSS positioning (most likely absolute) to make it appear as a pop-up. It also looks like they're using the CSS arrow trick to draw the speech bubble pointer, though it could also be accomplished with images.
If I were to develop this, I'd break it down into stages like this:
Get my pop-up into my HTML page, and make sure it's not appearing anywhere.
Make it show/hide when I wanted it to (either when the blue bar is clicked, or when the user mouses in/mouses out of the blue bar).
Make it show/hide where I want it to (near the blue bar)
Make it look better (work on the CSS and get the pointer to work properly)
Convert that work into a second-level popout. The second level is going to be the exact same technique, but maybe the CSS classes are going to be different so the second bubbles look different and have the pointer at a different position.
Of course, you don't have to develop this functionality yourself. There are also a number of jQuery plugins you could use, as well as Bootstrap's popover component.
Im trying to recreate the script that rdio (http://rdio.com) has created for their player footer. when you click on footer, a panel slides up nicely and to reveal more content. another example is by teehan lax; the top dropdown http://www.teehanlax.com/ but theirs doesn't support firefox properly.
I came across this snippet, http://www.dynamicdrive.com/dynamicindex17/dddropdownpanel.htm
But its not clean as rdio's or teehan.
any thoughts on library they might using?
We're just using basic CSS transitions, and adding and removing classes. The z-index of the bottom bar is set such that it appears in front of everything else, and the class changes control how the content is changed.
You can accomplish the same height changes with jQuery quite easily, as described here: https://stackoverflow.com/a/4965097/1309238
We are making this template in our language, Persian, that is right-to-left (RTL). Template address
Now, all parts are RTL, except that the submenu that opens to the right side,
Question: What changes should be made to this css file of the template, so that submenu width will be the same as its menu width? Or: How can the submenu be made to open on the left side?
Be aware that am not talking about the text in the submenu (text is rtl now as you see in picture)
Just a thought off the top of my head ...
I suspect you would adjust this line:
width: 140px; /*width of sub menus*/
to reflect a narrower width for your needs.
If you need to do this dynamically, you may have to do some work with Javascript to check the text being applied, then adjust the class reference to a custom class reference ... OR ... apply the new width to the element directly ... once the drop down entries have been filled.
Ah, ok, I see now. The problem here is that with the particular component you are using, you cannot adjust it with only CSS. The reason why is that the Javascript completely rewrites your CSS for that portion of the menu every time a user hovers their mouse over it. You're going to have to do some adjustment inside the Javascript to solve this.
There are several ways to go about this, I'm only going to get into one of them.
One way to solve this is adjust how the menu is rewriting it's CSS on the fly for the submenu. In this case, you can have the Javascript write a negative value in for the "left:" CSS element attribute to have the submenu position itself to open as you're wanting. Note: With this solution, this may not work in older Internet Explorer browsers - I'm not sure if that's a concern here. However, it will work just fine in the modern browsers (at least the ones I've been poking about with).
Open up your copy of the ddsmoothmenu.js file, that's the little bugger that is causing all the problems here.
The change needs to be done in the
$curobj.hover(function(e){..})
function. Stay with me, I'll explain...
That function is calculating the starting left position of your submenu once the user positions their mouse over the main menu choice. Namely, this line here is the culprit:
var menuleft=header.istopheader && setting.orientation!='v'? 0 : header._dimensions.w
As you can see, it is returning a '0' for you, which means it will anchor the left side of the submenu, forcing it to spill out to the right like it does now.
However, fear not!
Since you need the submenu to anchor on the right side and spill out to the left instead, we simply need to change this from assuming '0' to a formula with a little intelligence behind it.
What we need, is for the Javascript to find the correct position to anchor the submenu on the right. We do this by helping the routing understand what the "right side" of the "header" element is.
To find this, we simply take the width of the header, remove from that the left offset of the a-href tag that actually contains the header text (this is in case of any margins that exist - which this has some set in the CSS) and then remove the actual width of the submenu UL tag itself. Now as a sidenote, I wish I didn't have to use something so imprecise as assuming the header is the first child, but... eh... sometimes you work with what you got.
So comment out the line I mentioned above, and put this line in instead:
var menuleft=((header._dimensions.w-header.childNodes[0].offsetLeft)-header._dimensions.subulw);
And from what I see, it should open out towards the left as you were needing it to do in the first place.
Hope this answer helps more than my previous one.
