Hi Jessica,
if you are using a Datagrid2 :
- check the styling config of your Datagrid and toggle "Compact" to true.
this will add a Mendix class to your rows which makes the rows thinner.
Otherwise :
- yes, you will need to create a Css class as descriped here.
Hope this helps,
Best Regards
If you are using data grid 2, Follow below steps;
1. double click each cell, navigate to appearance tab
2. Add a class name to Dynamic cell class. for example add as 'cell-height'
3. Now add this class to your UI Resource module/styling/web/core/custom_styles.scss.
example class:
.cell-height{
height:20px;
}
Please note that this class name you should put into all cells of datagrid
