How to hide the Umano SlidingupPanel when clicking outside the panel

Hiding the Umano SlidingUpPanel on Outside Click

The Umano SlidingUpPanel is a useful component for adding interactive panels to your web applications. However, you may want to automatically hide the panel when the user clicks outside of it. This article will guide you through the process of implementing this functionality.

Understanding the Concept

To achieve this, we’ll use a combination of JavaScript event listeners and CSS to detect clicks outside the panel and trigger the closing action.

Implementation Steps

1. Adding the Event Listener

Attach an event listener to the document that listens for ‘click’ events. This listener will be responsible for determining if the click occurred inside or outside the panel.

    document.addEventListener('click', function(event) {
      // Code to handle click events
    });
  

2. Checking for Click Location

Inside the event listener, we’ll check if the clicked element is the panel itself or any of its descendants. If the click is outside the panel, we’ll hide it.

    document.addEventListener('click', function(event) {
      if (!event.target.closest('.sliding-up-panel')) {
        // Hide the panel
      }
    });
  

3. Hiding the Panel

Use the appropriate method to hide the panel. The method will depend on the specific implementation of the Umano SlidingUpPanel. In most cases, you can simply toggle a CSS class that controls the panel’s visibility.

    document.addEventListener('click', function(event) {
      if (!event.target.closest('.sliding-up-panel')) {
        document.querySelector('.sliding-up-panel').classList.add('hidden'); // or use a custom class
      }
    });
  

Complete Example

Here’s a complete example demonstrating the implementation:

    <div class="sliding-up-panel">
      <h3>Sliding Up Panel</h3>
      <p>This is the content of the panel.</p>
    </div>

    <style>
      .sliding-up-panel {
        // Styles for the panel
        position: fixed;
        bottom: 0;
        left: 0;
        width: 100%;
        background-color: #fff;
        padding: 20px;
        transition: transform 0.3s ease;
      }

      .hidden {
        transform: translateY(100%);
      }
    </style>

    <script>
      document.addEventListener('click', function(event) {
        if (!event.target.closest('.sliding-up-panel')) {
          document.querySelector('.sliding-up-panel').classList.add('hidden');
        }
      });
    </script>
  

Additional Considerations

• Panel Opening Mechanism: Ensure that the click event listener does not interfere with the way you open the panel. You might need to temporarily disable the listener or use an alternative opening mechanism.
• Customizations: Tailor the code to match your specific panel styles and functionality.

Conclusion

By implementing the techniques described above, you can seamlessly hide the Umano SlidingUpPanel when the user clicks outside of it. This provides a user-friendly experience, allowing users to easily close the panel and return to the main content of the page.
