Topic: Add/Remove of select options multiplies nested wrappers

3aalliance free asked 4 years ago

Expected behavior Hello, Support Team, While using mdb-select dynamic adding/removing options would work stable.

Actual behavior I use this html code of mdb-select:

Ingress Port

I add option to this select with this function:

$('#ingressDpidField').on('change', function() { var optionList = ''; optionList = optionList + 'One'; optionList = optionList + 'Two'; optionList = optionList + 'Three'; $('#inPortField').append(optionList); });

Then I remove options with this function:

$('#egressDpidField').on('change', function() { $('#inPortField option[value="1"]').remove(); $('#inPortField option[value="2"]').remove(); $('#inPortField option[value="3"]').remove(); $('#inPortField').materialSelect(); });

At first glance everything works good. Although if repeat the above many times in development tool I see that select-wrapper multiplies its own nested copies infinitely Snapshot On some cycle browser became slow. This behavior does not depend on hw/sw platform and browser type/version.

I tried to remove select after removing of options with $('#inPortField').materialSelect({ destroy: true }); , but this does not help. Please help me to understand what I am doing wrong and fix an issue.

Than you!

Can you give us some estimate on when this is going to be fixed, I want to know if I should wait or if I should fix it by myself.

Grzegorz Bujański staff commented 4 years ago

Unfortunately not. At the moment I can't say when it will be fixed

This is a critical problem!

It's the same thing , seems like the mutation observers on the select doesn't disconnect properly when destroy is called
