I used to use the following code to ask for confirmation before deleting an item:

<?php if (MD_CanDelModule()) { ?><a href="index.php?MD_Action=DelModule&MD_ModuleId=<?php echo $MD_ModuleId ?>" onClick="return ConfirmLink('Are you sure?');"><i class="far fa-trash-alt" aria-hidden="true"></i></a>

This does no longer seem to work with MDBootstrap 5 so I chaned it to:

<a href="index.php?MD_Action=DelModule&MD_ModuleId=<?php echo $MD_ModuleId ?>" class="popconfirm-toggle" data-mdb-popconfirm-mode="modal" data-mdb-message='Are you sure?'></class><i class="far fa-trash-alt pe-auto" aria-hidden="true"></i></a>

No I do have a popup asking a question, however no mater what I select the URL is still loaded, how can I make it wait until I made a selection and only load the url when I press OK?
