I have a modal that seems to stop rendering footer completely randomly.

So far what worked was clearing cache, logging out, restarting browser (brave). Anything I do with code has no effect (comment out all JS, all HTML).

Now it's down to sample syntax

    <lightning-quick-action-panel header="header">
        <div slot="footer">

Down to this result:

enter image description here

Looking via chrome dev tools I can see slds-hide class is not removed from footer for some reason.

Edit: I also use this component wrapped in aura's lightning:isUrladdressable and force:lightningQuickActionWithoutHeader context, where this bug appeared again. Disabled all extensions I use to no avail. Restarting Brave browser did the trick tho.

  • I can see the lightning-quick-action-panel component is still on Beta. maybe that's the reason of its inconsistent behavior. by any change do you have any CSS implemented on your component?

  • I don't have any CSS. Starting to suspect it might be brave or some extension issue. Will try to isolate once it appears again.

    This is still an issue, and the component is out of beta since Summer GA. Commented Oct 13, 2022 at 17:41

I had a similar issue, using lightning-quick-action-panel made footer stop rendering in random behavior.

Adding a custom class to enforce visibility did the trick for me, at least as a workaround.

inside my component.html:

<div slot="footer" class="force-visible">

in component.css

    visibility: visible !important;

Using api version 55.0


My work-around was to put the footer outside the lightning-quick-action-panel tag. class="slds-modal__footer" ensure the correct styling.

<lightning-quick-action-panel class="slds-is-relative" header={title}>
    <div class="" if:true={showContent}> content </div>
<div  class="slds-modal__footer">
        label="Send Request"

I upgraded to version 57, and it started to be more stable.
