It allows you to specify the placement of the label. You can select one of the available options:
  • Top - It allows you to align the text at the top of the Multi-select widget.
  • Left - It aligns the text to the left of the Multi-select. When you select Left alignment, you get additional settings that you can use to control the alignment and define the text's width.
    • Alignment - With the help of alignment, you can define the placement of the text in accordance with the position of the Multi-select widget. You can choose:
      • Left - It aligns the text to the widget's left boundary that is away from the Multi-select widget.
      • Right - It aligns the text closer to the Multi-select widget.

Displaying Data

Multi-select options can be populated from a data source like an API / Query by transforming the incoming data to an array of (label, value). The transformation can be performed using javascript. So if the data is an array, we can transform it using the Array map function.
1
// Query1.data is assumed to be an array here
2
{{ Query1.data.map((row) => {
3
return { label: row.name, value: row.id }
4
})
5
}}

Filtering Data

A MultiSelect widget can be used to filter a dataset based on the user's input. The selected value can be passed to an API using**{{ multiselect1.selectedOptionValues }}** .
Server Side Filtering can also be enabled on the widget by enabling Server Side Filtering property.

Form Submission

Multi-select widgets can be used to capture from a fixed set of options inside a form such as gender, role, and status.
Some forms need to be pre-filled data from a table or API. We can bind the data to the default text property to enable this.
1
{{ Table1.selectedRow.gender }}
2
/**
3
* Binding this to the default option will update the selected option
4
* of the MultiSelect widget with the gender of the selected row in Table1
5
*/
