3 controls on the tree – select, expand, open

We have a tree with one click to select and double click to expand. This works well for our users and is something that would be better to keep unchanged.

enter image description here

Now we need to add another action to some of parent elements – to open this parent’s content in a new window (this contains not only child elements, but also additional info about the parent). What could be the best option for this?

Considered solutions:

A) Add “open” to the action bar – not ideal, because an action which is detached from its object may be not obvious and users may not look at the action bar.

enter image description here

B) Add a button on the parent element – if add it on every element it will be too many buttons. Maybe add to only the selected one, then the question is where to place it.

mysql – ¿Cómo evitar duplicado en el select option generado por PHP?

Estoy tratando de agregar un selected al option cuando exista un ID del cliente caso contrario que pase al default <option value="">Por favor, seleccioné un cliente...</option>, funciona bien al agregar el selected, pero el problema es que ese mismo option aparece dos veces, me lo duplica aparte me esta generando mal la estructura HTML del selected -> option.

Este es mi código:

$get_id = 3;

$stmt = $con->prepare("SELECT
                            id_cliente,
                            nombre_cliente
                        FROM cliente");
$stmt->execute();
$stmt->store_result();

if ($stmt->num_rows>0) {
    $stmt->bind_result(
        $id_cliente,
        $nombre_cliente
    );

    $select = '';
    $select .= '<select name="id_cliente">';
    $select .= '<option value="">Por favor, seleccioné un cliente...</option>';
    
    
    while ($stmt->fetch()) {
        if(1) {
            $select .= '<option value="'.$id_cliente.'"'; if($id_cliente === $get_id) $select .= 'selected="selected">'.$nombre_cliente.'</option>';
        }
        $select .= '<option value="'.$id_cliente.'">'.$nombre_cliente.'</option>';
    }
    $select .= '</select>';

    echo $select;
}

Y, este es el resultado que me esta generando:

<select name="id_cliente">
<option value="">Por favor, seleccioné un cliente...</option>
<option value="2"<option value="2">Cliente 1.</option>
<option value="3"selected="selected">Cliente 2.</option>
<option value="3">Cliente 3.</option>
<option value="4"<option value="4">Cliente 4.</option><option value="16"<option value="16">Cliente 5.</option>
<option value="17"<option value="17">Cliente 6.</option>
</select>

-- list each city once (no duplicates) and sort in descending alphabetical order.

select distinct customer_city as cities
FROM customers
ORDER BY customer_city ASC

-- left Los  Angeles
