Headline

Contrary to popular belief, Lorem Ipsum is not simply random text. It has roots in a piece of classical Latin literature from 45 BC, making it over 2000 years old. Richard McClintock, a Latin professor at Hampden-Sydney College in Virginia, looked up one of the more obscure Latin words, consectetur, from a Lorem Ipsum passage, and going through the cites of the word in classical literature, discovered the undoubtable source. Lorem Ipsum comes from sections 1.10.32 and 1.10.33 of "de Finibus Bonorum et Malorum" (The Extremes of Good and Evil) by Cicero, written in 45 BC. This book is a treatise on the theory of ethics, very popular during the Renaissance. The first line of Lorem Ipsum, "Lorem ipsum dolor sit amet..", comes from a line in section 1.10.32. The standard chunk of Lorem Ipsum used since the 1500s is reproduced below for those interested. Sections 1.10.32 and 1.10.33 from "de Finibus Bonorum et Malorum" by Cicero are also reproduced in their exact original form, accompanied by English versions from the 1914 translation by H. Rackham.

Open

<mc-dialog id="scrollable-dialog">
  <div slot="headline">Headline</div>
  <div slot="content">
    ...large content
  </div>
  <mc-button slot="actions" onclick="mcDialog.close()">Close</mc-button>
</mc-dialog>

Fullscreen

Fullscreen dialogs are for compact window sizes only

Headline

Open

<mc-dialog id="fullscreen-dialog" fullscreen>
  <div slot="headline">Headline</div>
  <div slot="content">
    ...content
  </div>
</mc-dialog>

Fullscreen with form

Fullscreen dialogs with forms can prevent closing based on changes

Change form

Open

      <mc-dialog id="fullscreen-dialog" prevent-close fullscreen>
        <div slot="headline">Change form</div>
        <div slot="content">
          <!-- form[id] required -->
          <form id="fullscreen-form" method="dialog" onsubmit="console.log('submitted')">
            <div style="font-size: 14px; margin-bottom: 8px;"><strong>X</strong> checks for form changes and presents dialog</div>
            <div style="font-size: 14px; margin-bottom: 24px;"><strong>Save</strong> will validate the form</div>
            <mc-textfield label="Required" supporting-test="Required" required value="one"
              class="outlined"></mc-textfield>
          </form>
        </div>
      </mc-dialog>

Prevent close and prevent navigation

Prevent close will prevent the dialog from being closed when scrim (backdrop) is clicked and ESC key is pressed

Prevent navigation will show a confirm dialog, asking the user if they want to navigate away

Open

// also available globally on window
import { mcDialog } from '@thewebformula/materially/services';
// import { mcDialog } from '@thewebformula/materially';

const answer = await mcDialog.simple({
  headline: 'Question',
  message: 'Are you sure?',
  preventClose: false, // default false
  preventNavigation: true // default false
});
