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:
-
labelMode: "outside" | "static" | "floating" | "hidden"
Specifies label display mode. -
labelLocation: "top" | "left" | "right"
Specifies whether to place outer labels above, to the left, or to the right of corresponding editors. The latter location is not demonstrated in this example. -
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.
To get started with the DevExtreme Form component, refer to the following tutorial for step-by-step instructions: Getting Started with Form.
