        </div>
        </div>

there is ten sectors , and for each of them it will show another div with description and details

<div class="sector" id="sector1">
                <div class="priceflex">
                    
                    <p>Original Kvalitet </p><p class="priceitem">2299.99,-</p>
                    </div>              
                <div class="priceflex">
            <p>TopKvalitet </p><p class="priceitem">1199.99,-</p>
                    </div>
                    <div class="priceflex">
            <p>KobiKvalitet  </p><p class="priceitem">799.99,-</p>
                    </div>
                    
            </div>

i'm using this code to show and hide each div(sector)

var modal = document.getElementById("myModal");
var btn = document.getElementById("myBtn");
var btnClose = document.getElementById("btnClose");

var divState = {};
function showhidesector(id,id2) {
    if (document.getElementById) {
        var divid = document.getElementById(id);
        divState[id] = (divState[id]) ? false : true;
        for (var div in divState){
            if (divState[div] && div != id){ 
                document.getElementById(div).style.display = 'none'; // hide
                divState[div] = false; 
            }
        }
        divid.style.display = (divid.style.display == 'block' ? 'none' : 'block');
    }
}

so my question is , is there anyway to achieve this without assigning id's for each element ? because i have to create a modal for every mobile device (about 120 devices)

You can simplify your code by using querySelectorAll() to retrieve all the p.click elements, then looping through them to add the same event handler to each one.

The related sector can targeted by using a data attribute to store the selector for each element. Try this:

document.querySelectorAll('p.click').forEach(el => {
  el.addEventListener('click', e => {
    let sectorId = e.target.dataset.sectorid;
    document.querySelector(sectorId).classList.toggle('show');
  });
});
.sector { display: none; }
.sector.show { display: block; }
<div class="hyperclicks">
  <p class="click" id="click1" data-sectorid="#sector1">Udskiftning af Skærm</p>
  <p class="click" id="click2" data-sectorid="#sector2">Udskiftning af Batteri</p>
  <!-- other p elements here... -->
</div>

<div class="sector" id="sector1">
  <div class="priceflex">
    <p>Original Kvalitet (SECTOR 1)</p>
    <p class="priceitem">2299.99,-</p>
  </div>
  <div class="priceflex">
    <p>TopKvalitet </p>
    <p class="priceitem">1199.99,-</p>
  </div>
  <div class="priceflex">
    <p>KobiKvalitet </p>
    <p class="priceitem">799.99,-</p>
  </div>
</div>

<div class="sector" id="sector2">
  <div class="priceflex">
    <p>Original Kvalitet (SECTOR 2)</p>
    <p class="priceitem">199.99,-</p>
  </div>
  <div class="priceflex">
    <p>TopKvalitet </p>
    <p class="priceitem">299.99,-</p>
  </div>
  <div class="priceflex">
    <p>KobiKvalitet </p>
    <p class="priceitem">399.99,-</p>
  </div>
</div>

Nest div.sector within div.click. Use event delegation. If div.click is clicked add a class that hides all non hidden div.sector within div.hyperclicks. Then remove that hidden class from div.sector from the clicked element.

document.addEventListener(`click`, handle);

function handle(evt) {
  if (evt.target.matches(`.click`)) {
    evt.target.closest(`.hyperclicks`).querySelectorAll(`div .sector:not(.hidden)`)
      .forEach(d => d.classList.add(`hidden`));
    evt.target.querySelector(`.sector`).classList.remove(`hidden`);
  }
}
.hidden {
  display: none;
}

.sector {
  margin-left: 2rem;
  color: green;
}

.click {
  margin: 0.8rem 0;
  cursor: pointer;
}
<div class="hyperclicks">
  <div class="click">Udskiftning af Skærm
    <div class="sector hidden">
      <div class="priceflex">
        <div>Original Kvalitet </div>
        <div class="priceitem">2299.99,-</div>
      </div>
      <div class="priceflex">
        <div>TopKvalitet </div>

        <div>KobiKvalitet </div>
        <div class="priceitem">799.99,-</div>
      </div>
