Showing and hiding a menu on button click, and hiding it with outside clicks

it fixes the issue The line $('ul.controls li.options').hide(); will probably hide your menu.
If this is the case, the test if ( OptionMenu.is(':visible') ) will always return false and show the menu.

Showing and Hiding of Objects in JQuery

wish help you to fix your issue .toggle(showOrHide) allows for a boolean to show or hide the element.
You could rewrite your example to look like this:
code :
$("#txtA").toggle(type === "A");
$("#txtB").toggle(type === "B");
$("#txtC").toggle(type === "C");

like below fixes the issue The .readLess doesn't exist when you bind the event. Try below code,
See alternate solution below for better code.
code :
var div = $(".overview").height();
var content = $(".overview").html();
$(".overview").css("height", "200px");
$(".overview").css("overflow", "hidden");

$(document).on('click', ".readMore", function() {
    $(".overview").html(content);
    $(".overview").css("height", "auto");
    $("#read").removeClass("readMore");
    $("#read").addClass("readLess");
    $("#read").html("Read less");
});

$(document).on('click', ".readLess", function() {
    $(".overview").css("height", "200px");
    $(".overview").css("overflow", "hidden"); 
});
var $overview = $('.overview');
var $read = $('#read');

var div = $overview.height();
var content = $overview.html();
$overview.css({
    "height": "200px",
    "overflow": "hidden"
});

$read.on('click', function() {
    var $this = $(this);
    if ($this.hasClass('readLess')) {
        $overview.css({
            "height": "200px",
            "overflow": "hidden"
        });

       $read.removeClass("readLess").addClass("readMore").html("Read More");
    } else if ($this.hasClass('readMore')) {
        $overview.html(content);
        $overview.css("height", "auto");
        $read.removeClass("readMore").addClass("readLess").html("Read less");

    }
});

React: Hiding/Showing an element while hiding the rest of the similar elements

like below fixes the issue Revealing just the one component's ingredients will be easier. Closing the rest will be a little trickier.
Revealing ingredients - Without Redux, you could add a state property isOpen. When you click on a button in that component it should change the state property isOpen to true. Hide/show the ingredients based on that state property value, which you can do in the markup (shown below) or with a class and a CSS rule.
code :
<div key={1}>
  showIngredients = () => { this.setState({isOpen: true}) }
  <button onClick={this.showIngredients}>Show ingredients</button>
  {this.state.isOpen && <div>Ingredients list</div>}
</div>
// parent
revealChild = (key) => {this.setState(selectedKey: key)}
...
<div>
  {children.map((child) => {
    return <Child onReveal={this.revealChild} key={child.key} isSelected={this.state.selectedKey == child.key}/>
  })}
</div>

// child
handleReveal = () => this.props.onReveal(this.props.key)
showIngredientsClass = () => this.props.isSelected ? 'visible' : 'hidden'
showButtonClass = () => this.props.isSelected ? 'hidden' : 'visible'
...
<button onClick={handleReveal} className={this.showButtonClass()}>Show ingredients</button>
<div className={this.showIngredientsClass()}>
  My ingredients
</div>

Delphi: Hiding/showing TWinControl objects in a form is pretty slow. How to get it faster?

seems to work fine Your controls are parented directly by the form. Instead create a panel with alClient align and set the panel's Parent to be the form.
When you create the edit controls, make their Parent be the panel. When you wish to hide the edit controls, hide the panel.
