Bootstrap Multiselect update option list on flow

Answer 1

In the doc I can read :

.multiselect('setOptions', options) Used to change configuration after initializing the multiselect. This may be useful in combination with .multiselect('rebuild').

Maybe you can't change your widget data by your initial way. In a correct way you should use setOptions method.

Else : With your way, maybe should you think about destroy your widget .multiselect('destroy') and create it again after.

Update after comment :

In the doc : ( you've linked )

Provides data for building the select's options the following way:

var data = [
    {label: "ACNP", value: "ACNP"},
    {label: "test", value: "test"}
];
$("#multiselect").multiselect('dataprovider', data);

So : When you get data from your ajax call, you have to create an array of objects ( it's the options in the select you want to have ) with the format like

var data = 
[
    {label: 'option1Label', value: 'option1Value'},
    {label: 'option2Label', value: 'option2Value'},
    ...
]

When your objects array is created, then you just have to call the method

$("#multiselect").multiselect('dataprovider', data);

Where data is your array of objects.

I hope I'm clear :/
