Angular Data GridCustomising Inputs & Widgets

Style text inputs, checkboxes, toggle buttons and range sliders.

Styling Text Inputs

Text inputs can be styled with a combination of CSS variables and selectors:

.ag-theme-alpine {
    --ag-borders-input: dotted 2px;
    --ag-input-border-color: orange;
}
.ag-theme-alpine .ag-text-field-input {
    background-color: rgb(255, 209, 123); /* light orange */
}
.ag-theme-alpine .ag-text-field-input::placeholder {
    color: rgb(155, 101, 1); /* darker orange */
}

The CSS variables relevant to styling text inputs are:

--ag-borders-input Typea CSS border style and size (e.g. `solid 1px` or `none`)	Draw borders around inputs. Set this to a border style and thickness, e.g. `solid 1px` to enable borders, or `none` to disable borders.
--ag-input-border-color TypeCSS color (e.g. `red` or `#fff`)	Colour for borders around inputs, if enabled with --ag-borders-input
--ag-borders-input-invalid Typea CSS border style and size (e.g. `solid 1px` or `none`)	Draw borders around inputs when their content has failed validation. Set this to a border style and thickness, e.g. `solid 2px` to enable borders. Set to `none` to disable borders but ensure that you have added styles to differentiate invalid from valid inputs.
--ag-input-border-color-invalid TypeCSS color (e.g. `red` or `#fff`)	The color for the border around invalid inputs, if enabled with --ag-borders-input-invalid
--ag-invalid-color TypeCSS color (e.g. `red` or `#fff`)	The color applied to form elements in an invalid state
--ag-input-disabled-border-color TypeCSS color (e.g. `red` or `#fff`)	The border around disabled text inputs
--ag-input-disabled-background-color TypeCSS color (e.g. `red` or `#fff`)	The background colour of disabled text inputs
--ag-input-focus-box-shadow TypeCSS box-shadow value (e.g. `0 5px 10px black`)	box shadow around focussed inputs
--ag-input-focus-border-color TypeCSS color (e.g. `red` or `#fff`)	Colour of the border around focussed inputs. Set to `var(--ag-input-border-color)` if you do not want to change the border colour on focus.

Styling Checkboxes

The default styles of the grid disable the browser's native checkbox widget and create a custom appearance using icon fonts (see below for how to disable this).

See the Custom Icons documentation for how to replace the checkbox icons - the icons used are checkbox-checked, checkbox-unchecked, checkbox-indeterminate.

The colours can be controlled using the following CSS Variables:

.ag-theme-alpine {
    --ag-checkbox-background-color: yellow;
    --ag-checkbox-checked-color: red;
    --ag-checkbox-unchecked-color: darkred;
    --ag-checkbox-indeterminate-color: grey;
}

Styling Radio Buttons

Radio Buttons, such as those in the chart settings UI, are specialised checkboxes. They respond to the same colour variables as demonstrated above. They use the radio-button-on and radio-button-off icons.

Styling Toggle Buttons

Toggle Buttons, such as the "Pivot Mode" toggle in the above example, are specialised checkboxes. They respond to the same checkbox colour variables. In addition, they expose a few more variables for advanced customisation:

--ag-toggle-button-border-width TypeCSS length (e.g. `0`, `4px` or `50%`)	size of the toggle button outer border
--ag-toggle-button-on-border-color TypeCSS color (e.g. `red` or `#fff`)	colour of the toggle button outer border in its 'on' state
--ag-toggle-button-off-border-color TypeCSS color (e.g. `red` or `#fff`)	colour of the toggle button's outer border in its 'off' state
--ag-toggle-button-on-background-color TypeCSS color (e.g. `red` or `#fff`)	colour of the toggle button background in its 'on' state
--ag-toggle-button-off-background-color TypeCSS color (e.g. `red` or `#fff`)	colour of the toggle button background in its 'off' state
--ag-toggle-button-switch-background-color TypeCSS color (e.g. `red` or `#fff`)	colour of the toggle button switch (the bit that slides from left to right)
--ag-toggle-button-switch-border-color TypeCSS color (e.g. `red` or `#fff`)	border colour of the toggle button switch (the bit that slides from left to right)
--ag-toggle-button-width TypeCSS length (e.g. `0`, `4px` or `50%`)	width of the whole toggle button component
--ag-toggle-button-height TypeCSS length (e.g. `0`, `4px` or `50%`)	height of the whole toggle button component

Using or Browser Native Checkboxes or Creating Your Own

The default styles in ag-grid.css contain many CSS rules to implement the --ag-checkbox-* and --ag-toggle-button-* variables described above. If you want to use the browser's default UI or create your own then it's easier to start from a blank slate rather than attempting to override the default styles.

To achieve this, use the ag-grid-no-native-widgets.css CSS file instead of ag-grid.css.

Users of the Sass API can pass suppress-native-widget-styling: true to accomplish this.
