I have extended fe_users with four new fields. I need to make two of the fields multiple select fields. The values should come from a table ind the database. I have looked at the usergroup field to see if I cold get some hints on how to do it, but I need some more hints.

<femanager:form.select
                        id="femanager_field_tilbyder"
                        property="tilbyder"
                        multiple="multiple"
                        options="{allTilbyder}"
                        optionValueField="uid"
                        optionLabelField="title"
                        sortByOptionLabel="1"
                        class="form-control"
                        value="{femanager:Misc.GetFirst(objectStorage:user.tilbyder)}"
                        additionalAttributes="{femanager:Validation.FormValidationData(settings:settings,fieldName:'tilbyder')}" />

I guess that it is the “objectStorage:user.tilbyder” that I shuld look at, am I right or what should I do?
