How to set max-height of dropdown selection area?

In vuejs2 app having select input with rather big options list it breaks design of my page on extra small devices. Searching in net I found “size” property, but that not what I I need : I want to have dropdown selection, which is the default. Are there some other decision, maybe with CSS to set max-height of dropdown selection area.

Modeified PART # 1: I made testing demo page at http://photographers.my-demo-apps.tk/sel_test it has 2 select inputs with custom design and events as in this example link How to Set Height for the Drop Down of Select box and following workaround at js fiddle:

select{
    color: red;
}

<select onfocus='this.size=10;' onblur='this.size=1;' onchange='this.size=1; this.blur();'>
  <option>1</option>
  <option>2</option>
  <option>3</option>
  <option>4</option>
  <option>5</option>
  <option>6</option>
  <option>7</option>
  <option>8</option>
  <option>9</option>
  <option>10</option>
  <option>11</option>
  <option>12</option>
  <option>13</option>
  <option>14</option>
  <option>15</option>
  <option>16</option>
  <option>17</option>
  <option>18</option>
  <option>19</option>
  <option>20</option>
  <option>21</option>
</select>
<div>Popular Tags:</div>

are applied to the second select input and it does not look/work properly. I suppose it conflicts somehow with current desing. Can it be fixed somehow?

as that is vuejs2 page I know that there are some select components at https://github.com/vuejs/awesome-vue#select and I used some of them, like vue-select but I need to keep custom design so I try to use original select input...

Modified PART # 2 : I added 2 classes definitions :

.select-wrapper {
    height: 50px !important;
    overflow-y: visible !important;
    background-color: yellow !important;
}

.select {
    width: 100% !important;
    /* make it min-height*/
    min-height: 50px !important;
    border-radius: 25px !important;
    border-color: #555 !important;
    padding: 10px  !important;
    border:2px dotted red !important;
}

Also I set background-color and border to these classes to be sure that these classes are applied and !important to all properties. But it did not help. Could you please to take a look!

Thank you!

Solution 1:

Unfortunately, you cannot chant the height of a dropdown list (while using <select>). It is confirmed here.

you can build it yourself using divs & v-for (assuming you get the list from an outsource) and then you can style it as you wish.

apologies for barring bad news.

Solution 2:

Specifying height:50px is limiting the select to 50px. Use min-height instead. Also wrap the select element in a div with fixed height so that it'll overlap on content below and not push it down.

.select-wrapper {
  height: 50px;
  overflow-y: visible;
}

.select {
  width: 100%;
  /* make it min-height*/
  min-height: 50px;
  border-radius: 25px;
  border-color: #555;
  padding: 10px;
}

<span>Select height is limited to 8 options.</span>
<div class="select-wrapper form-column form-column-field">
  <select data-no-search="" data-placeholder="Выбрать год" onfocus="this.size=8;" onblur="this.size=1;" onchange="this.size=1; this.blur();" class="select select-no-search">

Fix for PART 2: In .selectCSS rule, either remove height:50px from main.css or in frontend.css add height: auto !important;.
Also you forgot to add onfocus="this.size=8;" onblur="this.size=1;" onchange="this.size=1; this.blur();" to the select which you are highlighting.

I've done above changes, locally, on your page using Dev Console, and here is how it looks: enter image description here
