How to specify features for a RichTextBlock in wagtail - wagtail

Question

I have a page that is using both a RichTextField and a StreamField with RichTextBlocks.
class TwoColumnBlock(StructBlock):
content = StructBlock(
[
("left_column", StreamBlock([("paragraph", RichTextBlock()), ("image", ImageChooserBlock())], max_num=1)),
("right_column", StreamBlock([("paragraph", RichTextBlock()), ("image", ImageChooserBlock())], max_num=1)),
]
)
class ScrollingExhibitPage(Page):
banner_text = RichTextField(blank=True, features=["bold", "italic"])
body = StreamField(
[("one_column", OneColumnBlock()), ("two_column", TwoColumnBlock())],
blank=True,
)
I'd like to have it so that anywhere a user is entering rich text, they are seeing the same options in the editor. However, I haven't been able to find any mention in the wagtail docs of how to set features for a RichTextBlock like you can for a RichTextField.
How would I go about doing that?

Answer 1

RichTextBlock accepts a features argument just like RichTextField does - this is documented at https://docs.wagtail.org/en/stable/reference/streamfield/blocks.html#wagtail.blocks.RichTextBlock.
class TwoColumnBlock(StructBlock):
content = StructBlock(
[
("left_column", StreamBlock([("paragraph", RichTextBlock(features=["bold", "italic"])), ("image", ImageChooserBlock())], max_num=1)),
("right_column", StreamBlock([("paragraph", RichTextBlock(features=["bold", "italic"])), ("image", ImageChooserBlock())], max_num=1)),
]
)

You can use WAGTAILADMIN_RICH_TEXT_EDITORS to configure different feature sets you can use different places. So you could have a full-featured version for your default and then a minimal editor that only allows bold and italics in other places. So an example from my code:
WAGTAILADMIN_RICH_TEXT_EDITORS = {
'default': {
'WIDGET': 'wagtail.admin.rich_text.DraftailRichTextArea',
# since sub, super, and a couple more are not included by default, we need to add them in this config
'OPTIONS': {'features': ['bold', 'italic', 'superscript', 'subscript', 'h1', 'h2', 'h3', 'h4', 'h5', 'h6', 'ol', 'ul',
'hr', 'blockquote', 'pre', 'link', 'embed', 'document-link', 'image']}
},
'minimal': {
'OPTIONS': {
'features': ['bold', 'italic', 'subscript', 'superscript', 'link']
}
}
}
And then when you want to use the minimal one, you can do something like:
description = RichTextField(
editor='minimal',
blank=True,
)
caption = blocks.RichTextBlock(
required=False,
label='Caption',
editor='minimal',
)
