#React-Components Some react components. Save mind.

EditableSelect

Just like its name, it's a editable select html element component.To get its value, use "instance.value".
Example:

const es=ReactDOM.render(
    <EditableSelect placeholder="enter or select">
      <opt value="0">option a</opt>
      <opt value="1">option b</opt>
      <opt value="2">option c</opt>
    </EditableSelect>
  );
  console.log(es.value);//the selected value. 
  //                      maybe the selected value("0"/"1"/"2") or the string user entered.

While inited:
While focused:

TreeMenu

It's like the right-click menu in windows, can have one-level sub-menus
Example:

ReactDOM.render(
     <TreeMenu
         container={data.container}
         menus={data.menuObjs}
         winWidth={winWidth}
         winHeight={winHeight} />,
     container
 );

Note:

This is customized for my project,you can change it!(By default, need jquery)
   The prop "menus" is important, it's a array of menu data:
      while no sub-menus:
        {
          text:'shown name',
          className:'menu class attribute',
          click:function(){...}//click event
        }

      while has sub-menus:
        {
          text:'shown name',
          className:'menu class attribute',
          subMenus:{}//sub-menus data object,like no sub-menus
        }
    className is unnecessary.
**menus fast preview**:
    __________________
   |                  |
   |      menu 1      |
   |__________________|  ______________
   |                  | |              |
   |      menu 2    > | | sub menu 2-1 |
   |__________________| |______________|
                        |              |
                        | sub menu 2-2 |
                        |______________|
                        
  above menu, need thus menu object array:
    [
      {
        text:"menu 1",
        click:function(){console.log('menu 1 clicked.');}
      },
      {
        text:'menu 2',
        subMenus:[
          {
            text:"sub menu 2-1",
            click:function(){console.log('sub menu 2-1 clicked.');}
          },
          {
            text:"sub menu 2-2",
            click:function(){console.log('sub menu 2-2 clicked.');}
          }
        ]
      }
    ]
