This feature allows users to add a link button to their email templates, specifying both the label and target URL. Upon clicking the link, recipients are redirected to the designated URL, facilitating easy access to relevant forms, web pages or resources directly from their email. > [!NOTE] > This control is only available for the Email-type Screen. See [Screen Types](/v1/docs/screens#screen-types). --- ## Add the Control to a Screen **Permissions** Your user account or group membership must have the following permissions to design a Screen unless your user account has the **Make this user a Super Admin** setting selected: - Screens: Edit Screens - Screens: View Screens See the [Screens](/v1/docs/permission-descriptions-for-users-and-groups#description-of-platform-permissions) permissions or ask your Administrator for assistance. Follow these steps to add this control to the [Screen](/v1/docs/screens): 1. [Create a new Email-type Screen](/v1/docs/create-a-new-screen) or [edit an existing one](/v1/docs/manage-screens#edit-a-screen). 2. From the Controls Menu on the left, expand the **Content Fields** category, and then locate the **Link URL** icon ![](https://cdn.document360.io/2d311614-fcb7-4424-8b4c-d4d3091eebeb/Images/Documentation/image(178).png) . 3. Drag and drop the control to the Screen Builder canvas. Existing controls in the Screen will adjust positioning based on where you drag the control. ![](https://cdn.document360.io/2d311614-fcb7-4424-8b4c-d4d3091eebeb/Images/Documentation/image(179).png) 4. Configure the Link URL control. See [Settings](/v1/docs/link-url-control#settings). 5. Validate that the control is configured correctly. See [Validate Your Screen](/v1/docs/validate-and-publish-a-screen). --- ## Settings The Link URL control has the following configurable settings in the Properties Panel: - [**Variable panel**](/v1/docs/link-url-control#variable-panel-settings) - [**Design panel**](/v1/docs/link-url-control#design-panel-settings) - [**Advanced panel**](/v1/docs/link-url-control#advanced-panel-settings) --- ### Variable Panel Settings Expand the **Variable** panel from the Properties Panel on the right to configure the following properties. #### Label Edit the default label that displays for this control if necessary. **New Link** is the default value. ![](https://cdn.document360.io/2d311614-fcb7-4424-8b4c-d4d3091eebeb/Images/Documentation/image(180).png) #### Link URL Enter the URL to display when a user clicks on this link. Variable values are allowed through mustache syntax.

The style changes the control's appearance but otherwise has no functional difference. Select from the following options: - **Primary**: Blue-colored background with white-colored **Label** text. This is the default option. - **Secondary**: Gray-colored background with white-colored **Label** text. - **Success**: Green-colored background with white-colored **Label** text. - **Danger**: Red-colored background with white-colored **Label** text. - **Warning**: Yellow-colored background with black-colored **Label** text. - **Info**: Teal-colored background with white-colored **Label** text. - **Light**: White-colored background with black-colored **Label** text. - **Dark**: Black-colored background with white-colored **Label** text. - **Link**: White-colored background with blue-colored **Label** text. ![](https://cdn.document360.io/2d311614-fcb7-4424-8b4c-d4d3091eebeb/Images/Documentation/image(182).png) --- ### Advanced Panel Settings Expand the **Advanced** panel from the Properties Panel on the right to configure the following properties: #### Visibility Rule Specify an expression that indicates the condition(s) under which this control displays. See [Expression Syntax Components](/v1/docs/feel-expression-syntax#show-or-hide-screen-builder-controls). If this setting does not have an expression, then this control displays by default. ![](https://cdn.document360.io/2d311614-fcb7-4424-8b4c-d4d3091eebeb/Images/Documentation/image(183).png) For example, this control displays if the variable value **tip** is **1.** > [!NOTE] > Visibility Rules > > - To make this control hidden until another control contains a value, enter the **Variable Name** setting value of that control to this control's **Visibility Rule** setting. > - [Visibility rules override custom CSS settings.](/v1/docs/screen-design-best-practices#visibility-rules-override-custom-css-settings) #### Device Visibility Select on which device types this control displays: - **Desktop**: The control displays only on desktop devices.

As a best practice, use the same **CSS Selector Name** value on different controls of the same type to apply the same custom CSS style to all those controls. ![](https://cdn.document360.io/2d311614-fcb7-4424-8b4c-d4d3091eebeb/Images/Documentation/image(185).png) Then, use this name in the [Custom CSS](/v1/docs/custom-css#apply-css-to-specific-processmaker-screen-controls) feature to apply CSS styling to this control as follows: ```css [selector='Link Email'] {    color: blueviolet; } ``` > [!NOTE] > CSS Best Bractices > > - [Editing a CSS name to represent this control in custom CSS syntax](/v1/docs/screen-design-best-practices#css-selector-naming-best-practice) > - [Visibility rules override custom CSS settings](/v1/docs/screen-design-best-practices#visibility-rules-override-custom-css-settings)
