// Show/Hide (10-June-2006)
// by Vic Phillips http://www.vicsjavascripts.org.uk

// To Show or Hide an Element
// Increases or decreases the height of an element between specified maximum and minimum heights.
// Optionally the element display may set to 'display:none' at the minimum height

// ***** Application Notes

// **** The HTML Code
// The element to Show/Hide must have a style 'position:relative;' or 'position:absolute;'
// e.g.
// <div id="fred1" style="position:relative;overflow:hidden;display:none;top:20px;left:20px;width:500px;height:5px;background-color:red;" ></div>
//

// **** Execution
// The effect is executed from an event call to function 'zxcShowHide'
// e.g.
// <input type="button" name="" value="Show/Hide" onclick="zxcShowHide('fred1',200,5,5,true);"/>
// where:
// parameter 0 = the element object or unique ID name. (object or string)
// parameter 1 = the maximum height. (digits)
// parameter 2 = the minimum height. (digits)
// parameter 3 = the height change increment. (digits)
// parameter 4 = optional true=display:none at minimum height. (true, false or omit)
//
// Note:
// if the initial height is less than the maximum height the height will be increased,
// if greater or equal to the maximum height the height will decrease.
//

// **** Show/Hide the Previous Element
//
// There may be more than one application on a page
//
// A customising variable 'zxcHideLast' if set to true
// Allows the Last Hide/Show Element to be Hidden.
//


// **** General
//
// All variable, function etc. names are prefixed with 'zxc' to minimise conflicts with other JavaScripts
// These characters may be changed to characters of choice using global find and replace
//
// The Functional Code (about 1K) is best as External JavaScripts.
// The Functional Code size may be reduced by including only the required functions.
//
// Tested with IE6 and Mozilla FireFox



// **** Customising Variables

var zxcHideLast=true; // if true Allows the Last Hide/Show Element to be Hidden.


// ***** Functional Code= NO NEED to CHANGE
