Advanced Select (selectEx) Element

The live selectEx field uses the Bootstrap Select (selectpicker) jQuery plugin, not vue-multiselect.

Common Configuration Properties

Property	Type	Description
type	String	Must be "selectEx"
label	String	Field label
model	String	Model key that stores the selected value
values	Array / Function	Available choices. If a function is used, it is called with (model, schema)
placeholder	String	Placeholder/title shown by the selectpicker
disabled	Boolean	Disables the select
fieldOptions	Object	Options passed into $(el).selectpicker(...)

values and Object Items

If values contains objects:

• fieldOptions.value defines which key becomes the stored value
• fieldOptions.name defines which key is shown as the option label

If those keys are omitted, the component falls back to:

• id for the stored value
• name for the visible label

Multi-Select

Set:

{
  "fieldOptions": {
    "multiSelect": true
  }
}

This maps to the rendered select element's multiple attribute.

Example Schema Snippet

{
  "type": "selectEx",
  "label": "Choose a Category",
  "model": "selectedCategory",
  "values": [
    { "id": 1, "name": "Electronics" },
    { "id": 2, "name": "Books" },
    { "id": 3, "name": "Clothing" }
  ],
  "placeholder": "Search or select a category",
  "fieldOptions": {
    "value": "id",
    "name": "name"
  }
}

Runtime Notes

• The component requires the Bootstrap Select library to be loaded globally.
• The field refreshes the selectpicker UI when the model changes.
• For single-select mode, the component renders a blank option with null value unless multiSelect is enabled.
