Ways to stop Bootstrap collapse from displaying depending on a certain condition in bs5 framework

I've been struggling to figure out how to prevent a collapsible panel from opening or showing if a specific value is null. Despite multiple attempts, I haven't had any success.

HTML

<a href="#" data-bs-toggle="collapse" data-bs-target="#infoBox" aria-expanded="false" aria-controls="infoBox"></i>
  
<div class="collapse m-3" id="infoBox">some ifos ...</div>

First attempt:

var someVal;
var infoBox = document.getElementById('infoBox')
infoBox.addEventListener('show.bs.collapse', function () {
    // console.log(e.target);
    if (someVal == null) return;
})

Second attempt:

var someVal;
var infoBox = document.getElementById('infoBox');
var bsCollapse = new bootstrap.Collapse(infoBox, {
    show: false,
    dispose: true
})
infoBox.addEventListener('show.bs.collapse', function (e) {
    // console.log(e.target);
    if (someVal == null) return bsCollapse;
})

Unfortunately, neither of these methods seem to be effective.

Answer №1

To prevent the default action, make sure to use the e.preventDefault() function.

var toggle = false;

$("#wrapper").on('show.bs.collapse', function (e) {
    if (!toggle) {
      e.preventDefault();
    }
});

  <div class="collapse m-3" id="infoBox">some information ...</div>
