Question: default value for Type: Countries (Multiselect)

[jelmer-devries]

Hi Pim community,

As you people might know there is a data component named Countries which can be found under the select dropdown. How would we specify it to have all countries selected at default?

Because as you can see there is none selected at default.

Also how and where would we integrate a button with JavaScript for example to select and deselect all countries? Sorry if this question seems a bit noob, but we just dived into PimCore and overall it's great software, thanks for that!
