Multiple dependent select boxes - javascript

I have 12 select boxes all filled up with their own specific array elements (also 12 arrays in total) and all of them are dependent on each other. I managed to make them all dependent on first select box, which means if I select an element in first select box, the rest of the information related to the first select box will be displayed on other select boxes. My problem is that I don't know how to filter the select boxes when I randomly select a value from a random select box.
Ex: I select a random value from one of the select boxes, now the other select boxes should be filled with the elements that are related to the first randomly selected value.

AngularJS. When changing the selected item in one combobox, how to clear the selected item in another combobox?

I have two combobox.
They are connected to each other. When an element is selected from the first combobox, the other combobox receives the corresponding data.
But when I select another item from the first combobox, the second combobox still shows the selected item from the generated data on the first select. The question is how to make it so that when an element is selected from the first combobox, the second one becomes clear and shows the standard writing?

Antd - Multiple select boxes remove items already selected

I have multiple antd select boxes rendered in a list. Options are populated via an array variable. If I have a value chosen in one select box I don't want to render it as an option in other select boxes. Do I just have to store a list for each select box for options or is there a simpler solution?

React Semantic Ui dropdown set dynamically

I am using react-semantic-ui
Here is the scenario:
I have two (2) dropdowns with placeholders, I am setting the 2nd Dropdown's option dynamically when I choose from the 1st dropdown. Then I would choose an item from the 2nd dropdown.
Then, If I changed the value of the 1st dropdown, it should change the values of the 2nd dropdown again, I have no problems with that but I want to set the placeholder back again
Summary: First I chose an item from the 1st dropdown, that sets the options of the 2nd dropdown. Then I choose an item from the 2nd dropdown, then I choose AGAIN from the 1st dropdown and that resets the options of the 2nd dropdown but that placeholder is not showing anymore.

Glitch fix for chosen multiselect dropdown

Example Fiddle
Description:
I have applied chosen plugin for a multiselect dropdown
The first option is "Any"
Those who are accustomed with chosen dropdown,they know that when an option is selected(from chosen multiselect) and presented in the dropdown textarea-like field, you will see it disabled from the list menu automatically.
When the first option "Any" is be selected, then all the other options from the list menu is also disabled.
When the "Any" option is removed from the dropdown textarea-like field(deleting by clicking on the cross with the selected option),then again all the options are enabled.
Requirement:
If we select any option from the dropdown, then its presented in the textarea-like filed, denoting that its being selected.
First select any option except "Any".
It will be displayed on the textarea-like field.
Now Select "Any".
Any will be displayed in the textarea-like field, and the previously selected option(s) is also being displayed in the textarea-like field.
I need the previously options selected to be removed from the textarea-field
How can I achieve this functionality?
You can define what happens in your if statement that checks to see if the Any option is selected
if (params.selected && params.selected == "Any") {
// disable the select
$('.chosen-select').val('Any'); // Select Any and remove everything else
And here is a demo
