# Bonds

This page of the data inspector shows all bonds and their property values as a data table. The page appears only if the current dataset contains bonds.

You can dynamically filter the displayed list of bonds by entering a Boolean expression in the input field at the top of the table. Consider, for example, the table shown in the screenshot: Here, the Compute property modifier had been used to compute and assign the `Length` property to each bond (last table column). To selectively list only those bonds that are very long, let’s say longer than 1.5 Angstroms, we can enter the expression `Length > 1.5` into the filter field. Multiple criteria can be combined using logical AND and OR operators. For a detailed description of the expression syntax, see the Expression Selection modifier. To reset the filter and show the full list of bonds again, use the X button.

The `Topology` bond property contains the indices of the two particles connected by a bond. This information may be used to select the bonds connected to a particular particle. For example to select all bonds adjacent to the first particle (particle index 0), we could use the following filter expression:

    Topology.A==0 || Topology.B==0
