How to include in table of contents the list of figures and list of tables?

Question

How to include in table of content the "Table of contents", "List of figures" and "List of tables"? All are generated with function Table of contents, but they will not appear in generated table of contents even if they have proper style of headings - Heading 1, as other chapter.
I get this in generated Table of contentes of my dissertaion thesis:
Table of contents
Preface
Table of contents <- missing
List of tables <- missing
List of figures <- missing
Introduction
Main
Conclusion
Is it ok, that generated lists are not included in table of contents?

Answer 1

You've just confused me.
My understanding of how this is set up is that either:
This is a book, and there is a master TOC that includes all book documents and a document-specific TOC in each component file, or
This is a single file and there is one master TOC that includes all sections and a section-specific TOC that includes only the individual section.
In the first case, I think you would want two TOC styles set up, one that includes the chapter heads (if I understood how you said this worked) for the for the master, and you would include all docs in the book when you generate it, and a second style for the individual chapters, with the subheadings you want to include.
In the second case, it would be similar, but instead of only one style to cover the section TOCS, I think you would need to create a unique set of pargraph styles for the headings in each section (they can all be the same format, based one section, just with unique names), and then make a TOC style for each section that includes only the styles from that section.
OK,  wait a sec. I just reread what you said: "Another thing: when the numbers are "linked" and updating well, they  display indide a little box. Not a text box, but a kind of little frame  around the numbers. That frame makes it imposible to delete just one  number: when the TOC says that Section 6.1 is in page 135, for example,  you cannot delete just the 5, it deletes, not just the 3 numbers, but  also the doted tab."
I think these are NOT normal TOCs created by using Layout > TOC (but you could replace them with ones that are, if you set up your styles properly and the text you want to include is appearing on the pages). Those little boxes you mention sound like cross-references, which should update automatically without any intervention at all. Unfortunately, cross-refs can be flakey, especially if they point to another document. I'd open the cross-refs panel and see if you need to recreate a bunch of links.
