Hi,

Next release ships big changes in CSS, meaningful changes in syntax and performance. To answer your question straight-forward I'd have to ask you to be a little bit more specific or, best, provide an example on codepen or JSfiddle. The documented feedback is used to constantly make MDB better, one step at the time.

With Best Regards,
Kuba

Hi there pwfraley,

Thanks for reaching out! Fixing the very issue you describe is part of the upcoming MDB 4.5 release, which should be out within a month. Until then, though, there are workarounds. Three steps to undertake in the mdb.js file:

1. Find options.find('li:not(.optgroup)').each(function (i) { (line 18944 depending on your compilation). There, swap the if (multiple) ... $newSelect.val($(this).text())} with the following:

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())
}

2. Add this bit before the found options.fint('li:not... part:

// Check for optgroups
var optgroup = false
if($select.find(‘optgroup’).length) {
 optgroup =true
}

3. Replace line select.siblings(‘ul.dropdown-content’).find(‘li’).eq(entryIndex).toggleClass(‘active’)(line 19177) with select.siblings(‘ul.dropdown-content’).find(‘li:not(.optgroup)’).eq(entryIndex).toggleClass(‘active’)

After these adjustments your material multiselect should fly.
Note: careful with characters like ”,”,",’ and '! These are OS-dependent - not paying attention while copy/pasting may break your code. Check yourself before you wreck yourself.

Let know whether this fixes helped your case.

With Best Regards,
Kuba
