There's StackExchange button with a dropdown layout on this site on the top-left side. If you click on it, it opens, if you click on somewhere else, it's hidden.
Is it possible to create a similar composition in vaadin application given a button and layout?
Two conditions are:
Know the state of the layout(hidden or shown) from the code(that's why javascript is not appropriate).
Button should expand and hide the layout and the rest area on the click should only hide it(the same as here with the StackExchange button).
Does anyone know the solution? Thanks a lot.
Two posibilities :
Native Vaadin : PopupView. Here's an example of using it in the Vaadin Sampler. No control over the placing of the popup, and showing the popup can't be controlled by anything other than the view itself.
Vaadin Addon : Overlays Allows you to overlay any component (e.g. a layout) relative to any other component, can can be controlled by a seaprate component (e.g. a button)

I am working with a Dashboard that has a menu. Let's take the attached menu as an example (which is NOT mine, I took a snapshot from a video).
Could you give me an idea of how I can do so that when pressing an option from the side menu, the content on the right side changes. Should I create an html document for each possible option and reference it from an "a href tag" or is there some other way to do it? Preferably the solution or idea does not involve react, angular or vue.
If you are not using any of SPA (Single page Application) then you must have to go for multipage activities where you need href on each option given in your main menu.
I am working on a React project where I have used CKEditor 4 on Material UI dialog. When I am trying to use advance options like Math. I am not able to type in, anything on input, textarea fields. I have searched for solutions but all the solutions are with respect to Bootstrap Modal. If anyone has faced the same issue using the Material UI dialog. It will be a great help if you can share the solution.
Solution for Bootstrap Modal: http://stackoverflow.com/a/18554395/778587
Material UI dialog: https://material-ui.com/demos/dialogs/
Attaching the Screenshot for the reference.
Steps to reproduce the issue. - Open https://codesandbox.io/s/vv50789765 for code example
Step 1: Open CKEditor and click on the picture icon highlighted in the screenshot.
Step 2: Once you click on the picture icon another popover will be opened with some input form elements. None of the input form elements is editable, I am not able to type anything in the form elements. Please refer the screenshot.
One of the Modal props is disableEnforceFocus:
If true, the modal will not prevent focus from leaving the modal while open.
Generally this should never be set to true as it makes the modal less accessible to assistive technologies, like screen readers.
Without this property set, every time you try to change focus to one of the input fields in the ckeditor image dialog, the Material-UI Dialog (which uses Modal) automatically brings focus back to itself.
Here's a version of the sandbox with disableEnforceFocus specified which then works:

I'm currently attempting to tab through some react components that I've (text inputs, checkboxes, radio buttons, etc) implemented (using material-ui). Something I've discovered is that tabbing through my components locally works as expected but as soon as I put it on the server, it skips through my checkboxes & radiobuttons (but tabbing to text inputs works fine).
The website that I'm displaying my react project on is built on backbone and I'm basically displaying an iframe with my react project inside that. Is it possible that this has some effect on a user's ability to tab through the components inside an iframe?
Thanks for your help!
With some help from above, I was able to figure out that when I render my react project inside the backbone project, some components such as my checkbox and radio buttons are wrapped inside a <span> tag and in order for it to be able to be tabbed I had to add the tagIndex attribute to it. Thanks everyone!
chatbox
profile view
So these are mockups for my social network project.
My question is that when a user logs in he is presented with this view.
There are two parent components THE LEFT PANE and RIGHT PANE.
THE LEFT PANE remains there for the whole session. BUT inside right pane I have to render
Chat box(when someone clicks on a friend from the list).
Pending request Component(When the see pending request button is
clicked)
Search Friends(When make friends button is clicked)
Profile View (When someone clicks on the interactive I button
Priorities:
I do not want to show the change in the address bar when any
component changes. So cannot use Browser Router.
Possible Solution but in doubt
I could use Conditional rendering by attaching some state variable
with each button click and when that button is clicked determining
the state i should render that specific component.
I could use Memory Router in react router in order to keep the code
clean and do not show the change in the address bar.
Help
CAN ANYONE WITH A GOOD EXPERIENCE IN REACT TELL ME IS THERE ANY OTHER WAY OF DOING THIS? AND IF NOT THEN WHICH IS A BETTER OPTION BETWEEN THESE TWO?
Pls refer to the images to get full idea about the situation.
thanks.
P.S. I can only post two links the other two components of pending request and make friends would be loaded the same way inside the right pane.
I think the best way would be to use the memory router Coz it would help to keep your code neat and understandable for reusability
In the snap you can see that after clicking the Add application link, this dialog box in the left hand side is appearing. This dialog box is a .jsp page. I don't have the access to the css files that this jsp is calling.
Now my question is :
I want to pull it down for some pixels, without using the css. Is it possible? if yes then how ? As you can see that due to its appearance in that position the back ground links are not visible.
The links and the form field(search for a text) are not key board accessible. How to make them keyboard accessible?
if u don't have access to .css, then in your present jsp, put style to that modal window if it is having a div. as,
In <div ... style="margin-top: 100px;">
aligning the layers definitely need some style, else browser cannot identify it
I want to pull it down for some pixels, without using the css. Is it possible?
It /might/ be (the specifics would depend on how it was implemented), but CSS is very much the right tool for this job.
The links and the form field(search for a text) are not key board accessible. How to make them keyboard accessible?
That depends on why they aren't keyboard accessible.
