类别在编辑中显示

In the edit post page, I show the category post for any post I have 3 Categories the problem Is the first category I can't see them For Example

Categories names :

1 - Saad

2 - Sayou

3 - Saay

if the the category post Is sayou

I see just like This

Category is = Saad List of categories has : Saay

I want to see the post category and all categories without category of the post

P.S : Sorry about my language I'm beginner in English :'(

my Code

<select id="category" name="category"  type="text" class="form-control">
<option value="<?php $rows_cat['Id_category'] ?>"><?php echo $rows['Category'] ?></option>
    <?php 
        while($rows_cat = mysqli_fetch_assoc($run_sql)){
        if($rows_cat['Category'] == $rows['Category'])
          {
            continue;
          }
        else {
        echo '<option value="'.$rows_cat['Id_category'].'">'. ucfirst($rows_cat['Category']).'</option>';
        }}
        ?>
        </select>
