Field group with selectmultiple fields

I am using a field group with 3 fields
1 selectmultiple
1 number
1 duration

My problem is that I don't know how to present the select multiple, it look like that



It should be like that



My custom html is this one

Any suggestions?

Hello

this should not happen

it would if you modified the type of field from single select to multiple select ??
and then tried to display the item

if you did you will need to reedit the items and fix the values and save them

In fact with a closer look, if I allow multiple values on this group, the 2 countries are on 2 entries of the group just like the countries field has multiple entries.

The countries field has always been multi select and never a single select..

I just created the group recently in order to manipulate the output easily. Is that the reason?

This website is the first I built with Flexicontent (6 or 7 years before) and it has been many time updated. Now I am building a complete redesign with the old datas.

Hello

i see now what happened

if use a multi-select that had data before you added it to fieldgroup
then its data will be have as multiple values in the fieldgroup !

you will need to edit them in item form, correct then and then resave the item form
