    Enable Tri-State

    Sometimes, it is essential for you to represent the answer in partially true state. To represent the partially true types, an indeterminate state option is present.

When only some of the files in a folder are selected, then the checkbox for that folder could be in indeterminate state.

    Styles Customization

  • <span style="margin-left: 15px">
        <ej-check-box id="check1" text="Primary" size="Medium" checked="true" css-class="success">
        <ej-check-box id="check2" text="Danger" size="Medium" checked="true" css-class="danger">
    </span>
  • css
  • <style>
            .success .e-chkbox-medium .e-chk-inact .e-chk-image,
