Component to render modal dialog as a Bootstrap Modal.

Usage #

<HxButton OnClick="HandleShowClick" Color="ThemeColor.Primary">Show modal</HxButton>

<HxModal @ref="myModal" Title="Modal title">
		Modal body
		<HxButton Text="Close" OnClick="HandleHideClick" Color="ThemeColor.Primary" />

Static backdrop #

When backdrop is set to ModalBackdrop.Static, the modal will not close when clicking outside of it.

Scrolling long content #

When modals become too long for the user’s viewport or device, they scroll independent of the page itself. Try the demo below to see what we mean.

You can also create a scrollable modal that allows scroll the modal body by setting the Scrollable parameter.

Vertically centered #

Set the Centered parameter to vertically center the modal.

Optional sizes #

Fullscreen modal #
