Topic: make multiselect a required form field
Hi,
If we consider the example Multiselect with options groups in https://mdbootstrap.com/docs/jquery/forms/multiselect/
Expected behavior
In case of an input field, the option required works as expected. Displaying a tooltip ("Fill out this field") and not submitting the form.
In case of a select field with the multiple, the option required has no effect and the form is submitted.
Actual behavior
When adding the required option and the user does not select any option, when clicking the submit button, there should be a tooltip displayed like "Fill out this field" and not submit the form.
Resources (screenshots, code snippets etc.)
<select name="netelement_location" form="bgp_lookup" class="mdb-select md-form" multiple required>
Can you please advise how to solve this in case of multiselect ?
thanks, is it possible to display sth like this ?
(this appears if I remove the multi select and use the required option)
it is not a tooltip, because it appears differently among browsers

Hi,
Unfortunately we don't have any options to different display of multiselect validate labels.

Thanks @Mateusz Łubianka what $('.needs-validation').addClass('was-validated'); actually does ?
Hi,
You can try to use validate option. Options for multiselect are the same like for select and you can find them here: https://mdbootstrap.com/docs/jquery/forms/select/#validation Try to use validate option and let me know, how it works.

Thanks. Using it as
<select name="netelement_location" form="bgp_lookup" class="mdb-select md-form validate" multiple required>
together with
$(document).ready(function() {
$('.mdb-select').materialSelect({ visibleOptions: 15, validate: true });
$('.select-toggle-all').css("display", "none");
});
the form still gets submitted if no option is chosen. what I am doing wrong ?
