Hide and Show Input Dropdown

[leandromatperei]

I have two different drop-down menus and I want to hide and show the second drop-down menu (IP) based on the first option.

<input type="dropdown" token="listaCategoria">
      <label>Selecione a Categoria:</label>
      <choice value="*">Todos</choice>
      <fieldForLabel>Categoria</fieldForLabel>
      <fieldForValue>Categoria</fieldForValue>
      <search>
        <query>index=funcionou 
| table Categoria 
| dedup Categoria
| sort Categoria</query>
        <earliest>0</earliest>
        <latest></latest>
      </search>
      <default>*</default>
      <initialValue>*</initialValue>
    </input>
    <input type="multiselect" token="multiselect" searchWhenChanged="true">
      <label>Selecione os endereços de IP</label>
      <prefix>IP IN (</prefix>
      <suffix>)</suffix>
      <delimiter>, </delimiter>
      <fieldForLabel>IP</fieldForLabel>
      <fieldForValue>IP</fieldForValue>
      <search>
        <query>index=funcionou
| table IP
 | dedup IP</query>
        <earliest>0</earliest>
        <latest></latest>
      </search>
      <choice value="*">ALL</choice>
      <default>*</default>
    </input>

Another detail, in the search, how should I refer to the two inputs? Ex:

Categoria=$listaCategoria$ OR \$multiselect$
