Foundation 6.4.3 Off-Canvas容器失效问题求助

Hey there! The main reason your Off-Canvas menu isn't showing up is that you're missing the trigger button needed to toggle it open. Foundation's Off-Canvas component is hidden by default—you need a button (or any interactive element) with the right data attribute to make it appear.

Let's walk through the fix step by step:

Step 1: Add the Toggle Button #

Inside your off-canvas-content container, add a button with the data-toggle attribute set to match your Off-Canvas container's ID (offCanvas). Here's how to update that section of your code:

<div class="off-canvas-content" data-off-canvas-content>
  <!-- Trigger button for Off-Canvas menu -->
  <button type="button" class="button" data-toggle="offCanvas">Open Menu</button>
  <!-- Your page content lives here -->
  Welcome !
</div>

Step 2: Confirm Your Existing Setup is Correct #

Good news—most of your code is already right:

• You've used the proper Off-Canvas wrapper structure (off-canvas-wrapper → off-canvas + off-canvas-content)
• All required data attributes are in place (data-off-canvas, data-off-canvas-content, data-close on the menu's close button)
• Foundation JS initialization ($(document).foundation();) is correctly placed after loading the Foundation script file.

Optional: Set Default Open State (If Needed) #

If you want the menu to be visible as soon as the page loads, add the is-open class to your Off-Canvas container:

<div class="off-canvas position-left is-open" id="offCanvas" data-off-canvas>

Once you add the trigger button, clicking it should slide out your menu exactly as expected.
