いいえ私は単純なメニューオプションを持っています;ユーザがそのカテゴリのメニュー項目divの1つをクリックすると、画面に表示されます。 *（すべてのコースは、デフォルトですべてのdivを表示する必要があります）。簡単なメニューオプションを作成しようとしました - クリックしても機能しません。
それがどのように見える：https://imgur.com/a/KZ9Ot
例： FOREXメニューをクリックした場合は、と外国為替に関連するdiv要素は、他のdivがdisapearする一方、すべてのコースメニューオプションをクリック上のデフォルトになります表示されますanotheがクリックされない限り、すべてのdivを表示します。
私の試み：すべてのdivは、IMをクリックするとdisplay:blockに変更すると、表示するdiv要素を見つけるためにswitchステートメントを使用して、display: none;を持っています。

$をtoggleClass（ 'ショー '）;（'-切り替えるコースボックス外為。'）。 この行は何ですか？ – Shaz
