1) This is a well known limitation - you cannot have "tall controls" (including HTML editor, grid, text area) in a column next to a standard column - there are several forum threads about this. Please have a look at them
If you want to do this you need to provide some CSS changes.
2) This is how you can override the default. You shouldprovide your own CSS file with the following settings:
.aw-column-multi .k-grid{
position: relative !important;
}
The above will override the default setting for ALL HTML controls in multi-column forms.
Or assign your own CSS class to a particular form and override for this form only:
.my-form-class .aw-column-multi .k-grid{
position: relative !important;
}
