The ExMenu/JS component provides menu-functionaly which includes top-level menus, context, popup, drop down or shortcut menus. A menu presents a list of items, commands, attributes, or states from which a user can choose. An item within a menu is known as a menu item, and may be configured to initiate an action, toggle a state on or off, or display a submenu of additional menu items when it is selected. A context menu is a menu in a graphical user interface (GUI) that appears upon user interaction, such as a right-click mouse operation. The ExMenu/JS is a HTML standalone-component, written in JavaScript, that uses no third-party libraries.
Every option of the Menu.Options type has associated a property of the control. For instance, the option:
debug {boolean}, indicates whether the control displays debug-information
is associated with the property:
Debug {boolean}, indicates whether the control displays debug-information
which means that the following statements are equivalent:
oMenu.Options = {debug: true}
oMenu.SetOptions({debug: true})
oMenu.Debug = true
oMenu.SetDebug(true)
where oMenu is an object of
Menu type
Parameters:

The client parameter indicates the control's client area as:
- array of [x,y,width,height] type that specifies the control's client area
- string, that specifies the identifier of the canvas within the document, so the canvas's client area becomes the control's client area
- HTMLCanvasElement, that specifies the identifier of the canvas within the document, so the canvas's client area becomes the control's client area
- null, indicates that the menu is displayed as a context/shortcut-menu at position (x,y) (of options). Use Open() method to open the shortcut/context-menu any time

- [captionWidth] or [cw], specifies the width to show the HTML caption of the item, where value could be a integer expression. A negative value indicates that no limitation is applied to the item's caption, so no truncate caption is shown. For instance [cw=128]
- [captionHeight] or [ch], specifies the height to show the HTML caption of the item, where value could be a integer expression. A negative value indicates that no limitation is applied to the item's caption, so no truncate caption is shown. For instance [ch=128]
- [height], specifies the height to display the item, where value could be a integer expression (it applies to all parts of the item). For instance [height=64]
- [width], specifies the width to display the item, where value could be a integer expression (it applies to all parts of the item). For instance [width=64]
- [button], associates a button with the item. The value could be a flag combination of Menu.ShowAsButtonEnum type, such as [button] or [button=1] makes the item to display a button, or [button=0] disables displaying any button.
- [spchk], indicates whether the sub-items/popup of giving item are shown when the item is checked. The value could be 0, which indicates that it has no effect, or non-zero to show the sub-item when the item is checked. For instance [spchk]

The string-representation supports the following flags:
- [id], specifies the item's identifier, such as [id=10].
- [align] {number}, horizontally aligns the caption. The align could be -1(full-fits the item), 0(left-alignment), 1(center), or 2( right-alignment) such as [align=2] right-aligns the item.
- [pad], specifies the item's padding (space between the menu border and the item content). The pad could be one or two numbers, separated by comma, such as [pad=2] or [pad=2,2]

- [captionWidth] or [cw], specifies the width to show the HTML caption of the item, where value could be a integer expression. A negative value indicates that no limitation is applied to the item's caption, so no truncate caption is shown. For instance [cw=128]
- [captionHeight] or [ch], specifies the height to show the HTML caption of the item, where value could be a integer expression. A negative value indicates that no limitation is applied to the item's caption, so no truncate caption is shown. For instance [ch=128]
- [height], specifies the height to display the item, where value could be a integer expression (it applies to all parts of the item). For instance [height=64]
- [width], specifies the width to display the item, where value could be a integer expression (it applies to all parts of the item). For instance [width=64]
- [button], associates a button with the item. The value could be a flag combination of Menu.ShowAsButtonEnum type, such as [button] or [button=1] makes the item to display a button, or [button=0] disables displaying any button.
- [spchk], indicates whether the sub-items/popup of giving item are shown when the item is checked. The value could be 0, which indicates that it has no effect, or non-zero to show the sub-item when the item is checked. For instance [spchk]
- [show], specifies how an item that has a check-box/radio-button should be displayed. The value could be any value of Menu.ShowCheckedAsSelectedEnum type. For instance [show=-1] (the exDisplayItemCheckHighlight value highlights the checked item)
- [showdis], makes the item to show as disabled, while it is still enabled. The flag is applied to all descendents. Any value not-zero indicates that the item is shown as disabled. For instance [showdis]
- [tab], indicates the identifier of the item that displays the sub-items of the current item. For instance: [tab=page] or [tab=1]
- [dis], disables the item. The flag is applied to all descendents. Any value not-zero indicates that the item is enabled. For instance [dis]
- [sep], specifies an separator item, such as [sep]. The value is ignored if provided. For instance [sep]
- [popupalign] or [pa], indicates how the sub-menu/popup/float is aligned relative to the parent item (Menu.ShowPopupAlignEnum). For instance [pa=1] (The exShowPopupAlignDown value indicates that the sub-menu/popup is shown down-aligned relative to the parent item)
- [shapes], specifies the shapes to be applied on the item only. For instance [shapes=dfitem(item),dfcap(cap)]
- [cursors], defines the mouse cursor to be displayed when pointing over a part of the item only. For instance [cursors=pointer(item)]

CSSColor or CSS legal color values can be specified by the following methods:
- Hexadecimal colors, is specified with: #RRGGBB, where the RR (red), GG (green) and BB (blue) hexadecimal integers specify the components of the color. All values must be between 00 and FF. For example, #0000ff value is rendered as blue, because the blue component is set to its highest value (ff) and the others are set to 00.
- Hexadecimal colors with transparency, is specified with: #RRGGBBAA, where AA (alpha) value must be between 00 and FF. For example, #0000ff80 defines a semi-transparent blue.
- RGB colors, is specified with the RGB(red, green, blue) function. Each parameter (red, green, and blue) defines the intensity of the color and can be an integer between 0 and 255. For example, rgb(0,0,255) defines the blue color.
- RGBA colors, are an extension of RGB color values with an alpha channel as RGBA(red, green, blue, alpha) function, where the alpha parameter is a number between 0.0 (fully transparent) and 1.0 (fully opaque). For example, rgba(0,0,255,0.5) defines a semi-transparent blue.
- HSL colors, is specified with the HSL(hue, saturation, lightness) function, where hue is a degree on the color wheel (from 0 to 360) - 0 (or 360) is red, 120 is green, 240 is blue. saturation is a percentage value; 0% means a shade of gray and 100% is the full color. lightness is also a percentage; 0% is black, 100% is white. HSL stands for hue, saturation, and lightness - and represents a cylindrical-coordinate representation of colors. For example, hsl(240, 100%, 50%) defines the blue color.
- HSLA colors, are an extension of HSL color values with an alpha channel - which specifies the opacity of the object as HSLA(hue, saturation, lightness, alpha) function, where alpha parameter is a number between 0.0 (fully transparent) and 1.0 (fully opaque). For example, hsla(240, 100%, 50%,0.5) defines a semi-transparent blue.
- Predefined/Cross-browser color names, 140 color names are predefined in the HTML and CSS color specification. For example, blue defines the blue color.
