Получение высоты элемента встроенного блока для заполнения родительского элемента

у меня есть контейнер с двумя элементами. Один из этих пунктов является select элемент, поэтому мне нужно установить size атрибут через HTML. Я хочу, чтобы другой элемент в контейнере растягивал свою высоту, чтобы соответствовать контейнеру. Я не могу этого понять. Я не хочу, чтобы явно задать высоту контейнера, потому что я не знаю размер этого выбора.

.container {
  padding: 5px;
  border: 1px solid black;
}

.container .column {
  display: inline-block;
  width: 40%;
  background-color: #AAA;
  padding: 5px;
  margin: 5px;
  vertical-align: top;
  height: 100%;
}

select {
  width: 100%;
}
<div class="container">
  <div class="column">Stretch to fill?</div>
  <div class="column">
    <select size="15">
            <option>Option 1</option>
            <option>Option 2</option>
        </select>
  </div>

Если table-cell вариант, вот способ сделать это:

.container {
  display: table;
  width: 100%;
  padding: 5px;
  border: 1px solid black;
}

.container .column {
  display: table-cell;
  width: 40%;
  background-color: #AAA;
  padding: 5px;
  border: 5px solid white;
  vertical-align: top;
  height: 100%;
}

select {
  width: 100%;
}
<div class="container">
  <div class="column">Stretch to fill?</div>
  <div class="column">
    <select size="15">
            <option>Option 1</option>
            <option>Option 2</option>
        </select>
  </div>

Если я понимаю, что вы говорите, вы стоите перед 100% высота столбцов

никакие ответы здесь не дали мне утешения, поэтому я пошел и искал правду. Я добавил немного больше css, чтобы сделать точку на расстоянии между двумя полями.

CSS:

 .wrapper {
  background-color:gray;
}

.container {
    margin: 25px auto;
    display: inline-flex;
}

.leftbox {
    height: inherit;
    display: inline-block;
    border: 1px solid #D7D2CB;
    background-color: #FFFFFF;
    border-radius: 5px;
    max-width: 550px;
    margin-right: 18px;
    align-items: stretch;
    padding: 15px;
    width: 100%;
}

.rightbox {
    height: 100%;
    display: inline-block;
    border: 1px solid #D7D2CB;
    background-color: #FFFFFF;
    border-radius: 5px;
    align-items: stretch;
    max-width: 300px;
    width: 100%;
    padding: 20px 15px;
}

HTML:

<div class="wrapper">
  <div class="container">
    <div class="leftbox">
      There is something here, I am not avoiding it.
    </div>
    <div class="rightbox">
      Probably something else here but much much much much much much much much much much much much much much much much much much much much much much much much much much much much much bigger.
    </div>
  </div>
</div>

пример, где мне также нужен псевдо-элемент:
