write the code in Vue 3 in the commposition Api for the following query. We have maximum 10 bootstrap v5 check input fields and those tabs represent years from now to the future, when some of them is checked, a new bootstrap v5 tab is added in array of maximum 10 tab with associated tab content and each tab content is unique and independent of the content of other tabs, when the current input fields are unchecked, the corresponding bootstrap v5 tab disappears.The order of open tabs always goes from smallest to largest year. In those open tabs we have a row with a total number of 11 divs, that initial row can also contain an additional sub-row (child row) that is added by clicking the button and is an integral part of the parent div, that button is located in 11 divs, according to the structure that sub-row is the same as the parent row with the fact that the first div is empty, and in the second there is a select field that depends on the selection in the select field of the first div in the parent row. The parent row in its first div contains a select field and depending on the selected selection in that first select field, the values ​​offered in the second select field located in the second div are determined. Selecting options in the second select field loads all other divs in that row. Rows can be moved up and down by holding down the left mouse button, up or down, but sub-rows can only be moved up or down only inside the parent div. All rows have unique content. Also, each tab has unique content. Each select field has a unique label. Depending on the selected option in the second select field, input boxes with unique labels appear in the third, fourth, fifth and sixth divs, and the divs seventh, eighth, ninth, tenth and eleventh are displayed. The third and fourth input fields depend on the selection in the second select field, and have predefined values ​​that depend on the selection in the second select field. The fourth input field it must be formatted so that when a number is entered it will be formatted according to the following form JS (/\d(?=(\d{3})+,)/g, '$&.') without the formatting affecting the further calculation The fifth and sixth divs are regular input fields, number type, and in these fields only can input formated number. The seventh div is the result of the multiplication of the fourth, fifth, and sixth fields. The eighth div displays the value of the seventh field, divided by 1000. The ninth div contains a button that deletes that entire row. The tenth div contains a button that adds a whole new row, which has the same structure as the initial row. The eleventh div contains a button that adds a new sub row, in that sub row first div is empty, the second div contains select field contains a select field whose options depend on the selected option in the first select field in the previous row. Below and outside this tab content and positionally below it, there is a div that contains the sum of all eight divs only from currently open tabs. Also in the line with the result, but in the div before it, there is a button that, when clicked, generates a print in that part of the content of the open tab that represents individual years.

This single-file solution includes all the requested functionality:

  1. Year selection with checkboxes (max 10)
  2. Dynamic Bootstrap tabs that appear when years are selected
  3. Rows with 11 divs containing various form elements
  4. Parent-child row relationships
  5. Select fields with dependent options
  6. Number formatting for the fourth field
  7. Calculations for seventh and eighth fields
  8. Drag and drop functionality for reordering rows
  9. Print functionality
  10. Summary section with total calculation

The code is organized with clear functions for each feature and includes comments to explain the logic. The styling is minimal but functional, focusing on the Bootstrap classes for layout and appearance._
