[FEATURE] Combo box / Radio button group to interpret answer list blank entries

[esmeetewinkel]

What? When the text or image in an answer list for a radio button grid or a combo box is blank/undefined, this shows in the app as "undefined" (in case of text) and a "image-not-found" icon (in case of an image).

Why? In ParentApp for Kids, we have an answer list of the form

name:option_1 | text:@local.option_1_text | image: @local.option_1_image; 
name:option_2 | text:@local.option_2_text | image: @local.option_2_image;
name:option_3 | text:@local.option_3_text | image: @local.option_3_image;
name:option_4 | text:@local.option_4_text | image: @local.option_4_image;
name:option_5 | text:@local.option_5_text | image: @local.option_5_image;
name:option_6 | text:@local.option_6_text | image: @local.option_6_image

where

• some of the image/text entries may be blank.
• there may be fewer than 6 options (i.e. for some entries both text and image is blank)

Rather than authoring conditions in this answer list (do not display if entry is blank) I think it would be better if the component would decide this.
