[mertsincan]

This change was made to make it easier for users to understand what the options are used for.

Options	Description
mergeSections	Used to merge PT sections of a component. Default value is true.
mergeProps	Whether to use Vue's mergeProps method to merge PT options. Default value is false. Ref: https://vuejs.org/api/render-function.html#mergeprops

Examples

• { mergeSections: true, mergeProps: false }

const Custom_Tailwind = usePassThrough(
    Tailwind,
    {
        panel: {
            header: 'my_panel_header'
        }
    },
    { mergeSections: true, mergeProps: false }
);

Output: 
panel.header.class => 'my_panel_header'
panel.title.class => Tailwind.panel.title.class

• { mergeSections: true, mergeProps: true }

const Custom_Tailwind = usePassThrough(
    Tailwind,
    {
        panel: {
            header: 'my_panel_header'
        }
    },
    { mergeSections: true, mergeProps: true }
);

Output: 
panel.header.class => [Tailwind.panel.header.class, 'my_panel_header']
panel.title.class => Tailwind.panel.title.class

• { mergeSections: false, mergeProps: true }

const Custom_Tailwind = usePassThrough(
    Tailwind,
    {
        panel: {
            header: 'my_panel_header'
        }
    },
    { mergeSections: false, mergeProps: true }
);

Output: 
panel.header.class => [Tailwind.panel.header.class, 'my_panel_header']
panel.title.class => undefined

• { mergeSections: false, mergeProps: false }

const Custom_Tailwind = usePassThrough(
    Tailwind,
    {
        panel: {
            header: 'my_panel_header'
        }
    },
    { mergeSections: false, mergeProps: false }
);

Output: 
panel.header.class => 'my_panel_header'
panel.title.class => undefined
