HTML code inside buttons with simple_form
Don't use content_tag. The following works:
<%= button_tag(type: 'submit', class: "btn btn-primary") do %>
<i class="icon-ok icon-white"></i> Save
<% end %>
In simple_form 3.0rc use :button button type (it passes your block to original ActiveView button helper):
<%= f.button :button do %>
<i class="icon-save"></i>
Commit
<% end %>
Or write additional button wrapper.
For additional info look into simple_form/form_builder.rb FormBuilder#button method.
I think you can't do it with simple_form. But I have good news for you. You should be fine using rails helper along side with simple form.
just do
button_tag(type: 'submit', class: "btn btn-primary") do
content_tag(:i, class: "icon-ok icon-white")
"Save"
end
Not sure if this works, even the syntax but it should give you a hint
