Select
‌Select / Dropdown widget is used to capture user input/s from a specified list of permitted inputs.

Displaying Data

A Dropdown's 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.
// Query1.data is assumed to be an array here
{{ Query1.data.map((row) => {
return { label: row.name, value: row.id }
})
}}

Filtering Data

A Dropdown can be used to filter a dataset based on the user's input. The selected value can be passed to an API using**{{ dropdownName.selectedOptionValue }} .

Form Submission

Dropdown 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
{{ Table1.selectedRow.gender }}
/**
* Binding this to the default option will update the selected option
* of the dropdown with the gender of the selected row in Table1
*/
Read more about submitting Input data to an API below.

Text

It allows you to set the display name for the Select widget. For example, if you want the user to select a Gender Type, you can enter the text as "Gender."
You can leave the text empty if you don't want any display name for your Select widget.

Position

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 Select widget.
  • Left - It aligns the text to the left of the Select widget. 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 Select widget. You can choose:
      • Left - It aligns the text to the widget's left boundary that is away from the Select widget.
      • Right - It aligns the text closer to the Select widget.
    • Width - With the help of width, you can define the number of columns in the grid that surrounds the widget. You can specify how close or far the text can be placed to the Select widget.
  • Auto - It automatically adjusts the position of the text based on the Select widget's height.
Columns are the dashed lines (-----) that surround a widget when you try to drag and drop it on the canvas.
