From the Phoenix LiveView documentation,
<input type="text" name={@form[:title].name} value={@form[:title].value} />
<div :if={used_input?(@form[:title])}>
<p :for={error <- @form[:title].errors}><%= error %></p>
</div>
<input type="text" name={@form[:email].name} value={@form[:email].value} />
<div :if={used_input?(@form[:email])}>
<p :for={error <- @form[:email].errors}><%= error %></p>
</div>
This can be used at the form level. However, if you want to handle at the input component level, how do we use used_input/1? In other languages we can give used_input(self) or something similar. How to do it here?
