This accordion utilizes the pre-made dropdown Webflow element.
The height of the .accordion-1_toggle needs to be set and that height needs to be the same in the .accordion-1_dropdown interactions on open and close. You also must use px units for the height of .accordion-1_toggle.
If you have an accordion where the content in .accordion-1_toggle is going to be variable you might want to consider another option because of the fixed height requirements.
These are popular in frequently asked questions and product/service feature sections.
We are working on building more accordions that can work in a variety of different scenarios.
