Default value Select Input
Question: Is there a default value that a option can have in select component? I am using LiveView
<.input field={@form[:theme]} value={"Roxo"} type="select"
options={[
{gettext("Vermelho Padrão"), "default_theme"}, {gettext("Roxo"), "purple_theme"}, {"Verde", "green_theme"}
]} />

remove “multiple” from select and dropdown works: <select id="theme" name="theme" class=""> {Phoenix.HTML.Form.options_for_select([{"Roxo", "purple_theme"}, {"Vermelho Padrão", "default_theme"}], @theme )} </select>

To set a default value, you do this in the form.
def mount(_params, _session, socket)
changeset = User.changeset(user, %{theme: "Dark"})
{:ok, assign(socket, form: to_form(changeset))}
If you are looking to set a default value that isn’t one of the options, you can add a prompt. Ie ‘Choose xxx’
<.input
field={@form[:theme]}
type="select"
prompt="Choose a theme..."
options={["Light", "Dark"]}
/>
