Prevent content swipe selection in EJ2 Angular Tab control

21 Dec 20245 minutes to read

The swipeMode property in the Tab component allows users to navigate between tabs using swipe gestures, improving the overall navigation experience. It supports both touch and mouse inputs, enabling intuitive tab switching.

However, in certain cases, such as when a tab contains critical elements like a form, accidental swipes can disrupt the user’s workflow. For example, if a user is filling out a form and mistakenly swipes, the tab might change unexpectedly, potentially leading to unsaved data or interruptions.

To address this, you can customize the swipeMode property based on the needs of the application. By adjusting this setting, you can balance smooth, intuitive navigation with protecting the user experience and safeguarding against accidental tab switches.

The following are the available swipeMode options for the Tab component:

• Both - By default, this option allows the user to swipe between tabs using both touch and mouse actions.
• Touch - This option allows users to swipe between tabs using touch gestures only.
• Mouse - This option allows users to swipe between tabs using mouse gestures only.
• None - This disables both touch and mouse swipe actions, preventing any unintended tab switches.
