I was hoping to get some help on creating a collapsible sidebar that is expanded on lg and higher views, but is collapsed with a (now visible) button to expand on tablet and mobile views (md or smaller).
So break it down: -How would I make my sidebar collapsible on mobile/tablet views? (xs, md, lg) -It need to be expanded in desktop views (lg, xl) -And have a toggle button that's hidden in large desktop views, but displays in small mobile/tablet views. -Do I need to write some custom JS? -Linked here are the BS4 Docs for Collapse, but I didn't understand how this would do what I need ( https://getbootstrap.com/docs/4.0/components/collapse/#options ). Maybe a JS person could help.
Thank you for your help!
//The Button
<h4 class="mb-3"><span class="text-muted">Search Filters</span>
<button class="navbar-toggler border"
type="button"
data-toggle="collapse"
data-target="#sidebar"
aria-expanded="false"
aria-label="Toggle filters">
<span><i class="fas fa-filter"></i></span>
</button>
</h4>
//The Sidebar
<ul id="sidebar" class="list-group mb-3">
<li class="list-group-item d-flex justify-content-between lh-condensed">
<div>
<h6 class="my-0">Header</h6>
<div class="input-group mb-3">

Well, with some help on other websites I figured out the solution. The guys at the Slack Bootstrap Help Channel were kind enough to point me in the right direction by linking a StackOverflow thread .
Using that link along with the Collapse Documentation at Bootstrap I was able to figure it out. Below is the answer...
// Used jQuery to create the new logic:
if ($(window).width() < 922) {
$('#sidebar').collapse({
toggle: false
});
} else {
$('#sidebar').collapse({
toggle: true
});
}
// Also, needed to add the .collapse class to the UL:
<ul id="sidebar" class="collapse list-group mb-3">
....
</ul>
I hope this helps others!
No need to use JS, use Bootstrap classes: https://getbootstrap.com/docs/4.1/utilities/display/#hiding-elements
You could do this:
//The Button: The class d-lg-none will hide the filters for large size (ie: it'll be visible on xs-s-md sizes only)
<h4 class="d-lg-none mb-3"><span class="text-muted">Search Filters</span>
<button class="navbar-toggler border"
type="button"
data-toggle="collapse"
data-target="#sidebar"
aria-expanded="false"
aria-label="Toggle filters">
<span><i class="fas fa-filter"></i></span>
</button>
</h4>
//The Sidebar : "d-none d-lg-block" will display the sidebar only on large size
<ul id="sidebar" class="d-none d-lg-block list-group mb-3">
....
</ul>
