Tomahawk htmlTag tag
This tag is used to use html tag for its child
component. This provides "value" attribute to specify the name of the
html tag to be used. For example, if we want to make any string as bold then
enclose it within <t:html> tag and set its value as "b" because
in html to make any character bold we use <b> tag. If we don't provide any
value to value attribute then all its child component are rendered but no no
html tag is applied on them.

This tag contains attributes given below :
- id : This is the value which is used to
uniquely identify the component within the closest container like form or
subview. The main thing to remember is that its value must be a static
value.
- binding : This attribute is used to specify
the property of the backing bean with which this component instance is to be
bound.
- rendered : Its default value is true.
If this attribute is set to true then this component is presented in
the page to the user. If false, then this component is not rendered.
- value : This attribute is used to specify the
name of the html tag to be applied.
- forceId : This is a boolean attribute with
default value false. If this attribute is set to true, the tag is forced to
render the id for the component exactly as mentioned in the id attribute of
the tag. The benefit of this attribute is that we can reference component by
id in the javascript. If we don't use this attribute with the true value
then the id for the component is presented in different format.
- forceIdIndex : This is a boolean attribute
with default value true. If this value is true then the the component
displays the index number in its id value if the component is in a list. If
this attribute is set to false then this component will not append index
number as suffix . If forcrId is set to false then its value is ignored.
- enabledOnUserRole : If the current user has
one of the roles listed in the enabledOnUserRole attribute then enabling or
disabling of the component is decided on the base of "disabled"
attribute. If disabled attribute is set to true then component is disabled
otherwise enabled. If the user is not in the above list then the component
is rendered disabled.
- visibleOnUserRole : If the current user has
one of the roles listed in the visibleOnUserRole attribute then processing
of the component is decided on the base of "rendered" attribute.
If the rendered attribute is set to true then component is not rendered
otherwise displayed on the page. On the other hand if the current user
is not in the above list then the component is not processed.
- style : It is used to set the CSS style
definition for the component.
- styleClass : It is used to set the CSS class
for the component. It is same as html class attribute.
