MultiSelect

The values of the control "MultiSelect" can be provided as static datasource (data formatted like a Json Array inside your template) or in case of a external datasource e.g. by referencing a HybridForms catalog by linking to the URL or by providing an oData source.

Static datasource:

<div
    id="technician"
    data-hf-control="MultiSelect"
    data-hf-options="{
        label: 'Technician',
        required: true,
        dataSource: [
            { name: 'Bauer, F', code: 'Bauer, F' },
            { name: 'Gruber, P', code: 'Gruber, P' },
            { name: 'Lanner, G', code: 'Lanner, G' },
            { name: 'Simon, R', code: '3521' },

        dataTextField: 'name',
        dataValueField: 'code'
    }"

Stored data

​

<div
    id="technician"

        label: 'Technician',
        dataSource: [
            { name: 'Bauer, F', code: 'Bauer, F' },
            { name: 'Gruber, P', code: 'Gruber, P' },
            { name: 'Lanner, G', code: 'Lanner, G' },
            { name: 'Simon, R', code: '3521' },
            { name: 'Herbert, W', code: '123456789012' }
        ],
        dataTextField: 'name',
        dataValueField: 'code',
        required: true   
    }"
></div>

For each MultiSelect inside your Forms there are two value pairs of stored data:

First the information for the MultiSelect itself...

{
    "id": "technician",
    "value": "3521|Lanner, G"
}

...and second for the selected value:

{
    "id": "technician_HFText",
    "value": "Simon, R|Lanner, G"
}
