I claim: 1. A collapsible canopy frame comprising: elongated side poles each having a side and an end; and a plurality of wheel assemblies each having a mounting post and a wheel and a wheel bracket and a wheel axle, the mounting post of each wheel assembly being attached to and extending from the wheel bracket and inserted into the side pole, being perpendicular to the wheel axle, and being supported on and extending transverse to a corresponding one of the elongated side poles to mount the wheel assembly to the side pole, and wherein the mounting post and the wheel axle extend in a common plane. 2. The collapsible canopy frame of claim 1, wherein each said wheel assembly is removably supported on the corresponding one of the elongated side poles. 3. The collapsible canopy frame of claim 1, wherein the mounting post of each said wheel assembly extends through the side of the corresponding one of the elongated side poles to which it is transverse. 4. The collapsible canopy frame of claim 3, further comprising a bracket in the interior of each corresponding one of the elongated side poles, wherein each said bracket and each said corresponding elongated side pole comprises an opening aligned with each other through which the mounting post of the corresponding wheel assembly extends. 5. The collapsible canopy frame of claim 4, wherein each said mounting post is removably secured in the corresponding bracket. 6. The collapsible canopy frame of claim 4, wherein the opening of each said bracket comprises a resilient compression material mounted therein, and wherein the resilient compression material has an opening that is smaller than an enlarged portion of the mounting post of the corresponding wheel assembly, such that the resilient compression material compressibly secures the enlarged portion of the mounting post in the bracket to secure the mounting post to the bracket. 7. The collapsible canopy frame of claim 1, wherein the side of each elongated side pole is a vertical side. 8. The collapsible canopy frame of claim 1, wherein the mounting post extends perpendicularly to the side of the corresponding one of the elongated side poles. 9. The collapsible canopy frame of claim 1, wherein the mounting post comprises an enlarged portion and a recessed portion, the enlarged portion being inserted into the side pole. 10. The collapsible canopy frame of claim 1, wherein the side pole has a square cross-section. 11. The collapsible canopy frame of claim 1, further comprising a plurality of foot brackets, wherein each said foot bracket is mounted at the end of a corresponding one of the elongated side poles. 12. The collapsible canopy frame of claim 11, wherein each foot bracket comprises a support plate. 13. The collapsible canopy frame of claim 11, wherein the mounting post of each said wheel assembly is removably mounted to a corresponding one of the plurality of foot brackets. 14. The collapsible canopy frame of claim 11, wherein each said foot bracket comprises a first side surface having a first post opening that extends therethrough and receives the mounting post of a corresponding one of the plurality of wheel assemblies. 15. The collapsible canopy frame of claim 14, wherein the first side surface of each said foot bracket comprises at least one resilient tongue that defines at least a portion of the first post opening and engages a recess in the mounting post of the corresponding one of the plurality of wheel assemblies to secure the corresponding one of the plurality of wheel assemblies thereto. 16. The collapsible canopy frame of claim 14, wherein each said foot bracket comprises a second side surface having a second post opening, laterally offset from the first post opening, that extends therethrough to receive the mounting post of the corresponding one of the plurality of wheel assemblies. 17. The collapsible canopy frame of claim 14, wherein each said foot bracket comprises a compression material mounted in the first post opening, wherein the compression material has an opening that is smaller than an enlarged portion of the mounting post of a corresponding one of the plurality of wheel assemblies, such that the compression material compressibly receives the enlarged portion of the mounting post of the corresponding one of the plurality of wheel assemblies to secure it thereto. 18. The collapsible canopy frame of claim 1, wherein the mounting post is fixedly attached to the wheel bracket. 19. The collapsible canopy frame of claim 1, wherein the mounting post comprises a shoulder that spaces the wheel from the side pole. 20. A collapsible canopy frame comprising: elongated side poles each having a side and an end; a plurality of wheel assemblies each having a mounting post and a wheel and a wheel bracket and a wheel axle, the mounting post of each said wheel assembly being attached to and extending from the wheel bracket, being perpendicular to the wheel axle, and being supported on and extending transverse to a corresponding one of the elongated side poles to mount the wheel assembly to the side pole, wherein the mounting post of each said wheel assembly extends through the side of the corresponding elongated side pole, and wherein the mounting post and the wheel axle extend in a common plane; and a bracket mounted at the end of a corresponding one of each of the elongated side poles, wherein each said bracket and each corresponding elongated side pole comprises an opening aligned with each other through which the mounting post of the corresponding wheel assembly extends. 21. The collapsible canopy frame of claim 20, wherein each said wheel assembly is removably supported on the corresponding elongated side pole. 22. The collapsible canopy frame of claim 20, wherein a portion of each said bracket is disposed in the interior of the corresponding elongated side pole. 23. The collapsible canopy frame of claim 22, wherein each said mounting post is removably secured to the corresponding bracket. 24. The collapsible canopy frame of claim 20, wherein the opening of each said bracket comprises a resilient compression material mounted therein, and wherein the resilient compression material has an opening that is smaller than an enlarged portion of the mounting post of the corresponding wheel assembly, such that the resilient compression material compressibly secures the enlarged portion of the mounting post in the bracket to secure the mounting post to the bracket. 25. The collapsible canopy frame of claim 20, wherein the mounting post of each said wheel assembly is non-rotatably mounted to the corresponding bracket. 26. The collapsible canopy frame of claim 20, wherein a bottom of the wheel is aligned with a bottom surface of the bracket. 27. A collapsible canopy frame comprising: telescoping elongated side poles each having an upper section and a lower section, wherein each said lower section comprises a side and an end; a set of edge scissor assemblies pivotably coupled between adjacent ones of the telescoping elongated side poles, the set of edge scissor assemblies having ribs that rotate relative to each other; and a plurality of wheel assemblies each having a mounting post, a wheel, a wheel bracket, and a wheel axle, the mounting post extending out from the wheel bracket and extending in a common plane with the wheel axle, and the mounting post of each said wheel assembly being inserted into and extending transverse to the side of a corresponding one of the telescoping elongated side poles. 28. The collapsible canopy frame of claim 27, wherein the mounting post is perpendicular to the wheel axle. 29. The collapsible canopy frame of claim 27, further comprising a foot bracket mounted at an end of one of the side poles, with a hole in the foot bracket aligning with a hole in the side pole, and wherein the mounting post is removably inserted through the aligned holes in the side pole and the foot bracket to mount the wheel to the side pole.
