What problem does this feature solve

使用TinyPro构建管理系统，用户在使用管理系统时候，操作表单数据时，往往需要查看相关联的业务数据，查看或者核对后，再返回当前页面填入和编辑数据，没有多页签，管理系统非常难使用，尤其涉及财务数据，数据是不能错的，用户只能记录到纸上，把需要的数据一一准备好，然后再打开要操作的页面进行处理。一般管理类系统要求必须支持多页签，没有多页签没法使用。

What does the proposed API look like

1、每点击一个菜单，也多页签位置多一个对应页面；
2、弹出对话框应该在页面内，切换多页签不影响对话框，切换回来时，页签内对话框所填写的内容保持原样。
3、页面内所有的状态在多页签切换时保持原样，选择的查询条件、翻页、选中的记录等，在页签切换回来时，均保持原样。

Title: ✨ [Feature]: I hope TinyPro will add a multi-page tab mode

What problem does this feature solve

What problem does this feature solve

Use TinyPro to build a management system. When users use the management system and operate form data, they often need to view the associated business data. After viewing or checking, they return to the current page to fill in and edit the data. There are no multi-page tabs, and the management system is very It is difficult to use, especially when it comes to financial data. The data cannot be wrong. The user can only record it on paper, prepare the required data one by one, and then open the page to be operated for processing. General management system requirements must support multi-page tabs. Without multi-page tabs, it cannot be used.

What does the proposed API look like

1. Every time you click a menu, a corresponding page will appear in the multi-tab position;
2. The pop-up dialog box should be within the page. Switching between multiple tabs does not affect the dialog box. When switching back, the content filled in the dialog box within the tab remains the same.
3. All the status in the page will remain the same when switching between multiple tabs. The selected query conditions, page turning, selected records, etc. will remain the same when the tabs are switched back.
