Ionic 6 & Vue 3 | Ion-Modal with Fixed Header, Cutting off Content

Ionic Framework Ionic Vue
1

I am trying to make an ion-modal with a fixed header.

When I use the following template, the bottom of my content is cut off from the viewport (big red arrow pointing to missing blue button)

Check out the screenshot.

Can anyone help me find the right template to make an ion-modal with a fixed ion-header?

curious why you are even using a modal here… seems like an uncommon UI pattern

I think having a modal with a fixed header and scrollable content is an extremely common design pattern. I interact with apps on a daily basis that utilize this pattern.

Design pattern aside, a modal should be able to have a fixed header and scrollable content.

In Ionic 4 with Angular I am able to create a ion-modal with a fixed header.

Is this no longer possible in Ionic 6?

The only way I found to fix this is to set a fixed height on the ion-header and set the --offset-bottom of the ion-content::part(scroll) to the negative of the ion-header height.

See here for an example.

If you are using Ionic 6 with Vue 3 and facing issues with the Ion-Modal component cutting off content due to a fixed header, there are a few steps you can take to resolve the problem:

1. Adjust the CSS of the modal: By default, the Ion-Modal component has a fixed position, which can cause content to be hidden behind a fixed header. You can try adding custom CSS to the modal to adjust its position or apply a top margin to push it down, allowing the content to be visible.
2. Use Ionic’s “safe-area” CSS class: Ionic provides a “safe-area” CSS class that helps handle issues with content being hidden behind fixed elements like headers. Apply the “safe-area” class to the modal’s content container or any relevant elements to ensure that they are properly positioned and visible within the viewport.
3. Set a higher z-index: If the fixed header has a higher z-index than the modal, it can cause the content to be obscured. Make sure to set a higher z-index for the modal or its content container to ensure it appears above the fixed header.
4. Adjust the header’s positioning: If the fixed header is causing issues, you can try adjusting its position. For example, you can make the header scrollable along with the modal’s content or make it absolute positioned so that it does not overlap with the modal.

/* Adjust the position of the modal /
ion-modal {
–position: relative; / or other positioning adjustments /
z-index: 999; / Set a higher z-index */
}

/* Apply the “safe-area” class to handle content positioning */
.ion-padding.safe-area {
padding-top: env(safe-area-inset-top);
}

Remember to adapt the code to your specific use case and customize it as needed. Additionally, referring to the official Ionic and Vue documentation, as well as the Ionic community forums, can provide further insights and solutions for any specific issues you might encounter.
