alignTo

public function alignTo( String/HTMLElement/Ext.Element element, String position, [Array offsets], [Boolean/Object animate] )
Aligns this element with another element relative to the specified anchor points. If the other element is the document it aligns it to the viewport. The position parameter is optional, and can be specified in any one of the following formats:
  • Blank: Defaults to aligning the element's top-left corner to the target's bottom-left corner ("tl-bl").
  • One anchor (deprecated): The passed anchor position is used as the target element's anchor point. The element being aligned will position its top-left corner (tl) to that point. This method has been deprecated in favor of the newer two anchor syntax below.
  • Two anchors: If two values from the table below are passed separated by a dash, the first value is used as the element's anchor point, and the second value is used as the target's anchor point.
In addition to the anchor points, the position parameter also supports the "?" character. If "?" is passed at the end of the position string, the element will attempt to align as specified, but the position will be adjusted to constrain to the viewport if necessary. Note that the element being aligned might be swapped to align to a different position than that specified in order to enforce the viewport constraints. Following are all of the supported anchor positions: 
Value  Description
-----  -----------------------------
tl     The top left corner (default)
t      The center of the top edge
tr     The top right corner
l      The center of the left edge
c      In the center of the element
r      The center of the right edge
bl     The bottom left corner
b      The center of the bottom edge
br     The bottom right corner
Example Usage: 
// align el to other-el using the default positioning ("tl-bl", non-constrained)
el.alignTo("other-el");

// align the top left corner of el with the top right corner of other-el (constrained to viewport)
el.alignTo("other-el", "tr?");

// align the bottom right corner of el with the center left edge of other-el
el.alignTo("other-el", "br-l?");

// align the center of el with the bottom left corner of other-el and
// adjust the x position by -6 pixels (and the y position by 0)
