If basket is full, another product disabled

Hey guys, i developed e-commerce symfony app.

My question is: If an item has been added to the cart, The date and delivery time of the first product are active for other products.

This is output of product page (empty basket): http://prntscr.com/136rmf2 this is output of another product page after basket filled by one product: http://prntscr.com/136rvbt

This is my twig code:

<div class="row">
  {% if baskets.data.hasBasket is defined and baskets.data.hasBasket %}
    <div class="col-12 mb-2">
     <input type="hidden" name="city_id" value="{{ baskets.data.baskets[0].county.city.id }}"/>
    	<select name="city_id_temp" class="city select_option" readonly="readonly" disabled="disabled">
                <option selected value="{{ baskets.data.baskets[0].county.city.id }}">
                                  {{ baskets.data.baskets[0].county.city.cityName }}</option>
         </select>
       </div>
          <div class="col-12 mb-2">
            <input type="hidden" name="county_id" value="{{ baskets.data.baskets[0].county.id }}"/>
           <select name="county_id_temp" class="county select_option" readonly="readonly" disabled="disabled">
                     <option selected value="{{ baskets.data.baskets[0].county.id }}">
                                  {{ baskets.data.baskets[0].county.countyName }}</option>
                       </select>
                            </div>

What i wanted to do: If basket filled i dont want to dont being disabled for another product delivery time. How can i fix that?
