How can I increase the height of a multi-line text box field in the modern version of the SharePoint online display form in a SharePoint list without using PowerApps>customize form?

Question

When I use PowerApps > Customize Form to increase the text box height of the mutli-line field (Description), the error message "Unable to find default display form" pops up because I'm creating a new version of the form with an expanded text box height. I need to increase the height of the text box, so that end users can easily read and update these multi-line field sections in the SharePoint list. How can I do so without invoking that "Unable to find default display form" error message?

Hello @Samantha Mojica ,

Welcome to Q&A Forum!

According to my research, in SharePoint Online modern page, changing the height of the field through Power Apps is the best solution.

For "Unable to find default display form" error, you can refer this case to solve your problem.

Please following steps:

1.Go to the list page and click Integrate >> Power Apps >> Customize forms

2.On the Power Apps page, select the multi-line text box and drag the mouse to change the height of the field and set Mode is Multiline.

3.Click File tab to save this form.

4.Then, click "Publish to SharePoint" button to publish this form

5.Go to the list page and refresh it, when you click New/Edit item you will see the below form:
