Rails - Custom html into simple_form label

问题

I'm trying to customize the output of a simple_form association, basically I need to display a checkbox label on two lines. My idea was adding a "br" tag into the "label", but unfortunately it gets escaped so it display actually "br" instead of going to a new line

I use a lambda for customizing the label output

<%= f.association :item, :as => :check_boxes, :collection => current_user.items, :label => false, :label_method => lambda { |item| "#{item.city.capitalize},<br> #{item.address}" }%>

this produces an escaped br into the label string, how could I display the label on two lines?

回答1:

call html_safe method on the string you want not to be escaped.

<%= f.association :item, :as => :check_boxes, :collection => current_user.items, :label => false, :label_method => lambda { |item| "#{item.city.capitalize},<br> #{item.address}".html_safe }%>

For those of you looking to have custom html in elements as the title of the OP's question suggests, you can do this:

= f.input(:Foo, label: "Foo <span>(Blah helper text blah)</span>".html_safe)

回答3:

Does html_safe help?

<%= f.association(....).html_safe %>

if not, then post an example app on github showcasing this issue, so we can debug it
