| Parameter | Description | | |
| ----------------- | -------------------------------------------------------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| type |
Prevents the card from shrinking when its width or height is set to auto. Useful when cards adjust their size to fit other elements in the tab. Set to True to disable shrinking. Leave it as default if no issues occur, as forcing this may cause unexpected layout behavior.
