I used the following code in my blueprint to define a multi select field:
header.headline.classes: type: select label: Classes multiple: true options: 'class1': 'foo' 'class2' : 'bar'
The field appears correctly, but when I choose some options and try to save the page, I get the following error message:
So I changed the code to :
header.headline.classes: type: select label: Classes multiple: true use: keys options: 'class1': foo 'class2' : bar validate: type: commalist
Now the error is gone but the values were saved instead of the keys and the multi select field shows no selected items.
classes: - 'foo,bar'
Am I doing something wrong ?
