I have a little problem with open one offcanvas from previous canvas. Generally I have canvas like this using bootstrap 5:
<button class="btn btn-primary" type="button" data-bs-toggle="offcanvas" data-bs-target="#offcanvasBottom" aria-controls="offcanvasBottom">Toggle bottom offcanvas</button>
<div class="offcanvas offcanvas-bottom" tabindex="-1" id="offcanvasBottom" aria-labelledby="offcanvasBottomLabel">
<div class="offcanvas-header">
<h5 class="offcanvas-title" id="offcanvasBottomLabel">Offcanvas bottom</h5>
<button type="button" class="btn-close text-reset" data-bs-dismiss="offcanvas" aria-label="Close"></button>
</div>
<div class="offcanvas-body small">
<button class="btn btn-primary" type="button" data-bs-toggle="offcanvas" data-bs-target="#secondoffcanvas" aria-controls="offcanvasBottom" data-bs-dismiss="offcanvas">Open second offcanvas</button>
</div>
</div>
second offcanvas:
<div class="offcanvas offcanvas-bottom" tabindex="-1" id="secondoffcanvas" aria-labelledby="offcanvasBottomLabel">
<div class="offcanvas-header">
<h5 class="offcanvas-title" id="offcanvasBottomLabel">Offcanvas bottom</h5>
<button type="button" class="btn-close text-reset" data-bs-dismiss="offcanvas" aria-label="Close"></button>
</div>
<div class="offcanvas-body small">
second content
</div>
</div>
My scenario:
Read "how it works"...
"Similar to modals, only one offcanvas can be shown at a time."
However, you can open one from the other. Programmatically show the 2nd when the 1st is hidden...
var offcanvasBottom = document.getElementById('offcanvasBottom')
var secondoffcanvas = document.getElementById('secondoffcanvas')
offcanvasBottom.addEventListener('hidden.bs.offcanvas', function () {
var bsOffcanvas2 = new bootstrap.Offcanvas(secondoffcanvas)
bsOffcanvas2.show()
})
