Topic: Multiselect is not working anymore

giorgio.ponza priority asked 6 years ago

From version 4.4.3, the multiselect is not working as expected. If you open your demo page JavaScript / Select, and you choose Option 2 & Option 3 on the multiselect, it will check Option 1 & Option 2. It seems that the previous option is checked. With version 4.4.1 the multiselect was working as expected

I investigated the problem. There is this line in mdb.js selected = toggleEntryFromArray(valuesSelected, $(this).index() - 1, $select); If i delete the -1, the multiselect works as expected. I don't know if this is the right solution, but it's a start :D

We are currently working on it. Please be patient.
For this moment You can change part of our file to this:

if (multiple) {
$('input[type="checkbox"]', this).prop('checked', (i, v) => {
return!v
})
if(searchable) {
if(optgroup) {
selected=toggleEntryFromArray(valuesSelected, $(this).index() -$(this).prevAll('.optgroup').length-1, $select)
} else {
selected=toggleEntryFromArray(valuesSelected, $(this).index() -1, $select)
}
} else if(optgroup) {
selected=toggleEntryFromArray(valuesSelected, $(this).index() -$(this).prevAll('.optgroup').length, $select)
} else {
selected=toggleEntryFromArray(valuesSelected, $(this).index(), $select)
}
$newSelect.trigger('focus')
} else {
options.find('li').removeClass('active')
$(this).toggleClass('active')
$newSelect.val($(this).text())
}

Regards

You should also add this code before: // Check for optgroups var optgroup = false if($select.find('optgroup').length) { optgroup =true }

And finally, the last change: From: select.siblings('ul.dropdown-content').find('li').eq(entryIndex).toggleClass('active') To: select.siblings('ul.dropdown-content').find('li:not(.optgroup)').eq(entryIndex).toggleClass('active')

The correct solution is to change in mdb.js code line from selected = toggleEntryFromArray(valuesSelected, $(this).index() – 1, $select) to selected = toggleEntryFromArray(valuesSelected, $(this).index(), $select); Exactly as Giorgio.Ponza wrote in his reply. Regards

Hi Mikołaj, this bug is still present in MDB JQuery 4.4.4. The correction was not that difficult, so i am a bit disappointed it's not still corrected. :D

Mikołaj Smoleński staff commented 6 years ago

Sorry Giorgio. It is our omission. We'll try not to forget it in the next release

This bug still exist in lates 4.4.5 Jquery version.

It seems that the fix proposed will solve the issue, but it breaks when the Multiselect has a Searchbox. Probably something like this works better: <pre>var index = (searchable) ? $(this).index() -1 : $(this).index(); selected = toggleEntryFromArray(valuesSelected, index, $select);</pre>
