    Form

    Overview

    The Form component builds a data entry UI for an object assigned to the formData property. The component displays and aligns label-editor pairs for each field in the bound object.

    You can use the editors on the right to modify the following properties:

    • labelLocation
      Specifies whether to display labels above or to the left of corresponding editors.

    • colCount
      Specifies the number of columns in the layout. To build an adaptive layout where the column count depends on the container width, set this property's value to "auto".

    • minColWidth
      Specifies the minimum column width. Use this property when the colCount property's value is "auto".

    • width
      Specifies the Form component's width.

    • readOnly
      Makes the Form editors read-only.

    • showColonAfterLabel
      Specifies whether the Form displays a colon after a label.
