Max selectable items: the number of options you can select in the field.
Readonly: with this option enabled users will not be able to change the value selected in the field.
Populate items from API: this option is meant for advanced users. You will need to enter the REST API Url. The information returned by your API needs to have the following format: [{value:your_value, label:your_label}].
Data format: in order to generate the items through the API you will need a value and label. This field will allow you to define the exact value and label returned by your script.
For example if your returned array has the syntax [{key:1, name: John}, {key:2, name: Jane}], the value you need to set in the field is : key,name.

Here you can set the values that will be available for selection in the field. You can set a value and label for each item
