Hiermenus Go Forth, IV:
Version 4 - The Page-Specific Parameters
HM_PG_ItemPadding
- Description
- Sets the padding (distance from item border to item text) of all menu items in the page. All menus, in all cascades (top-level and children) are affected.
HM_PG_ItemPadding overrides site-wide global settings declared in the external script.
- Value
- Pixels.
May be specified as:
- integer
- string
- string JS expression to be evaluated
- Example Values
- integer: 3
All menu items in the page will have 3 pixel padding.
string: "3"
All menu items in the page will have 3 pixel padding.
JS expression: "getPadding()"
A custom function that you have created will be called. The return value of this function will be the HM_PG_ItemPadding parameter, and all menus in the page will comply.
JS expression: "eval(HM_PG_FontSize) > 12 ? 6 : 3"
The complete JS code is included in the parameter declaration. In the above example, HM_PG_ItemPadding is 6 if HM_PG_FontSize is 12 or greater. If not, HM_PG_ItemPadding is 3. Notice that one parameter's value can be determined by another's. Also note that we evaluate the value of HM_PG_FontSize since it may be declared as an integer, string or JS expression.
- Default
- If this parameter is omitted the relevant Global Parameter value, set in the external script is used.
- Differences from Version 3 equivalent
- The itemPad parameter in Version 3:
- accepted only integer values.
- was mandatory.
In our next installment, Hiermenus Go Forth, V, we'll continue our look at the new Page-Specific Parameters.
