Does Coda have global fields or variables?

[Ben_Lee]

You can create a 1 row table with buttons and then create views of that table to display the same buttons on other pages. You can also hide gridlines for the table and have it appear just as a canvas button.

Global/reusable buttons/table views

You can have a table with controls, e.g. buttons. Then making (copying) a view of that table on multiple pages will give you the rendering of the same controls. You can configure it from any page, and it will be reflected on other pages. With canvas controls you cannot do that. You also cannot have a pair of table views where adjusting the filter/sort/columns/etc of one view would automatically change the same on the other view.
