Topic: Multi Select Setting Values

jamie priority asked 9 months ago


I am trying to dynamcially set the values of a multi select dropdown. using the example where we set the values directly is seems to work but if i put them into a variable first then they dont.

Hi,

It works fine for me. Here is the snippet https://mdbootstrap.com/snippets/standard/d-wajszczuk/3712145#js-tab-view. The variable just needs to be an object. There were unnecessary quotation marks.

Keep coding,
Dawid

thanks, i was trying to create a string from my data rather than creating an array

    const values = [];
        options = Array.from(document.querySelectorAll('#categories option'));
        for (var i = 0; i < cat.length; i++) {
            values.push(cat[i].categoryid);
            }
            const multiSelect = document.querySelector('#categories');
            const multiSelectInstance = mdb.Select.getInstance(multiSelect);
            multiSelectInstance.setValue(values);
